Welcome and Acknowledgements We cordially welcome you to 99th Annual Meeting of the Geologische Vereinigung at the GZG (Geowissenschaftliches Zentrum) of the Georg-August-Universität Göttingen. The central theme of this year’s conference is Earth Control on Planetary Life and Environment. We intended to bring together researchers from all fields of Earth Sciences and beyond to shape an attractive interdisciplinary program on the geological history of Planet Earth and its control over and interaction with biological evolution, development of habitats, environmental and climate change as well as history and culture of Homo sapiens. We hope that our organisational efforts and your scientific input will make the meeting a great success. Göttingen is an attractive city full of interesting history, young students, medieval buildings, and international flair. Göttingen hosts one of the traditional German universities where - amongst others - famous earth scientists such as Johann Frie- drich Blumenbach, J. F. L. Hausmann, Adolf v. Koenen, Hans Stille, Victor Moritz Goldschmidt, and Carl W. Correns worked. We are sure that you will enjoy your visit. We are thankful to the Deutsche Forschungsgemeinschaft (DFG), Akademie zu Göttingen, Junge Akademie, Ministerium für Wissenschaft und Kultur, Springer Verlag, E. Schweizerbart’sche Verlagsbuchhandlung, and Pearson Education Deutschland GmbH for financial support. We wish you all a successful meeting and a memorable time in Göttingen.

Abstracts (in first author alphabetical order) 1: TS2 Geology of Extreme Earth Environments, oral Synchronisation of historical and recent glacier fluctuations in the Inner Himalaya Achenbach H Geographical Institute, Department of Geography and High Mountain Geomorphology, 37077 Göttingen, Goldschmidtsr. 5, [email protected] Investigations were carried out north of Annapurna and Daulaghiri Himal. Here, the semi-aride climate and the relief situation cause glaciers being very suitable for mak- ing a historical glacier chronology. The glaciers visited are of continental type with a very small mass turnover. Hence, they are not sensitive to sudden weather changes (Oerlemanns & Reichert 2000). Due to the moderate relief the glaciers are free of debris or just covered with a thin layer of supraglacial till. Therefore it can be ex- pected that the glacier fluctuations are coupled directly to the long time climate con- ditions. During two expeditions (07,08) the geomorphology of 27 glacier forefields was mapped. Typically the recent glacier tongues end between 5200 and 5700 m asl. They are surrounded by laterofrontalmoraines up to 120 m high, which evidence a glacier stage (st. 1) 1 to 3 km in front of the current ice margin. As can be seen from photos taken by Kuhle (1982) as well as proved by lateralmoraines a last glacier stage (st. 4) took place in the 1970th. Here the glaciers ended some decameters to a few hundred meters outwards the recent ice fronts. In between of stage 1 and stage 4 two more glacier advances/stagnations could have been reconstructed (st. 2 and 3).The relation to neo glacial stages, fresh glacier striations and lichen findings document that stage 1 is the oldest detectable historical glacier stage in the Inner Himal. Derived from different climate proxies the coldest period within the “Little Ice Age” took place at the end of the 17th and at the beginning of the 18th century. Lower average temperatures also occured around 1820 and from 1900 to 19 (Zech et al. 2003). With the exception of the first half of the 19th century no significant precepetation changes could have been reconstructed for the last 400 years (Kayas- tha et al. 2008, Thompson et al 2000), so it is highly likely that the evidenced glacier stages are caused by the above mentioned cold periods.

We address the problem of automatic crater detection and age estimation. From initially small numbers of recognized craters and dated craters, i.e., 7895 and 1411, respectively, we progressively identify new craters and estimate their ages with Chang’E data and stratigraphic information by transfer learning using deep neural networks. This results in the identification of 109,956 new craters, which is more than a dozen times greater than the initial number of recognized craters. The formation systems of 18,996 newly detected craters larger than 8 km are esti- mated. Here, a new lunar crater database for the mid- and low-latitude regions of the Moon is derived and distributed to the planetary community together with the related data analysis. 1 College of Earth Sciences, Jilin University, 130061 Changchun, China. 2 Key Laboratory of Lunar and Deep Space Exploration, National Astronomical Observatories, Chinese Academy of Sciences, 100101 Beijing, China. 3 Key Laboratory of Symbol Computation and Knowledge Engineering of Ministry of Education, College of Computer Science and Technology, Jilin University, 130012 Changchun, China. 4 Department of Information Engineering and Computer ✉ Science, University of Trento, I-38122 Trento, Italy.

To the disappointment of nearly all concerned, the data they sent back was a sharp dash of cold water. The Martian surface was harsh and antibiotic and there was no sign of life. To two NASA scientists, James Lovelock and Dian Hitchcock, this came as no surprise - in fact, they would have been amazed to see Toxic gases and mass extinctions mean Earth isn't any evidence of life on Mars. A decade always life friendly (Image: Sarah Howell) before Viking, Lovelock and Hitchcock, both Enlarge image atmospheric scientists, had used observations of the Martian atmosphere to 1 more image deduce that there could be no life on the planet. From their research arose one of the most influential, ground-breaking scientific ideas of the 20th century - the Gaia hypothesis, named after the ancient Greek goddess of the Earth, a nurturing "mother" of life. But is it correct? New scientific findings suggest that the nature of life on Earth is not at all like Gaia. If we were to choose a mythical mother figure to characterise the biosphere, it would more accurately be Medea, the murderous wife of Jason of the Argonauts.

    Geological Society of America Special Paper 405 2006 The record of impact processes on the early Earth: A review of the first 2.5 billion years Christian Koeberl† Department of Geological Sciences, University of Vienna, Althanstrasse 14, A-1090 Vienna, Austria ABSTRACT Collisions and impact processes have been important throughout the history of the solar system, including that of the Earth. Small bodies in the early solar system, the planetesimals, grew through collisions, ultimately forming the planets. The Earth started growing ca. 4.56 Ga in this way. Its early history was dominated by violent impacts and collisions, of which we only have circumstantial evidence. The Earth was still growing and had reached ~70%–80% of its present mass when at ca. 4.5 Ga a Mars- sized protoplanet collided with Earth, leading to the formation of the moon—at least according to the currently most popular hypothesis of lunar origin. After its forma- tion, the moon was subjected to intense post-accretionary bombardment between ca. 4.5 and 3.9 Ga. In addition, there is convincing evidence that the Moon experienced an interval of intense bombardment with a maximum at ca. 3.85 ± 0.05 Ga; subsequent mare plains as old as 3.7 or 3.8 Ga are preserved. It is evident that if a late heavy bom- bardment occurred on the Moon, the Earth must have been subjected to an impact flux at least as intense as that recorded on the Moon. The consequences for the Earth must have been devastating, although the exact consequences are the subject of debate (total remelting of the crust versus minimal effects on possibly emerging life forms).

  • The Cronus Hypothesis – Extinction As a Necessary and Dynamic Balance to Evolutionary Diversification
    The Cronus hypothesis – extinction as a necessary and dynamic balance to evolutionary diversification Corey J. A. Bradshaw1,2 and Barry W. Brook1 1The Environment Institute and School of Earth and Environmental Sciences, University of Adelaide, Adelaide, South Australia 5005, Australia 2South Australian Research and Development Institute, P.O. Box 120, Henley Beach, South Australia 5022, Australia [email protected]; [email protected] Abstract The incredible diversity of life on Earth veils the tumultuous history of biodiversity loss over deep time. Six mass extinction events since the Cambrian species explosion (including the current Anthropocene), and many smaller extinction spasms, have terminated 99 % of all species that have ever existed. Evolution and extinction, as universal processes, have been unified previously under James Lovelock’s Gaia hypothesis, and most recently, under Peter Ward’s Medea hypothesis. Gaia (the Greek Earth mother) posits that life on Earth functions like a single, self-regulating organism, whereas Medea (siblicidal wife of Jason of the Argonauts) describes instead a self-destructive feedback where life ‘seeks’ to destroy itself. We argue that these contrasting views are actually extremes of a scale-invariant stability-entropy spectrum of speciation and extinction for all life on Earth, much as the abundance and stability of a metapopulation of an individual species is the emergent property of births, deaths and migration. In this context, we propose a new metaphor called the Cronus hypothesis (patricidal son of Gaia) to explain how these processes can be quantified with existing mathematical tools and so be used to describe the ebb and flow of life on Earth along a thermodynamic spectrum.

Their reveal their evolutionary history and process. formation and evolution record the history of the Solar System. Lunar craters have the same genesis, i.e., impacts create craters that Sixty years of triumphs in the lunar exploration projects look similar in a near-circular depression structure. This is the main accumulated a large amount of lunar data. Currently, there are basis for the identification of craters. Different experiences, i.e., the 9137 existing recognized craters. However, only 1675 of them have formation and long-term alteration, lead to craters having a different been determined age, which is obviously not satisfactory to reveal complex morphology. Typical characteristics can demonstrate the evolution of the Moon. Identifying craters is a challenging task differences in orders of magnitude in size of the diameters, e.g. the due to their enormous difference in size, large variations in shape largest craters have a diameter of a few hundred kilometers, whereas and vast presence.

  • Science Concept 3: Key Planetary
    Science Concept 6: The Moon is an Accessible Laboratory for Studying the Impact Process on Planetary Scales Science Concept 6: The Moon is an accessible laboratory for studying the impact process on planetary scales Science Goals: a. Characterize the existence and extent of melt sheet differentiation. b. Determine the structure of multi-ring impact basins. c. Quantify the effects of planetary characteristics (composition, density, impact velocities) on crater formation and morphology. d. Measure the extent of lateral and vertical mixing of local and ejecta material. INTRODUCTION Impact cratering is a fundamental geological process which is ubiquitous throughout the Solar System. Impacts have been linked with the formation of bodies (e.g. the Moon; Hartmann and Davis, 1975), terrestrial mass extinctions (e.g. the Cretaceous-Tertiary boundary extinction; Alvarez et al., 1980), and even proposed as a transfer mechanism for life between planetary bodies (Chyba et al., 1994). However, the importance of impacts and impact cratering has only been realized within the last 50 or so years. Here we briefly introduce the topic of impact cratering. The main crater types and their features are outlined as well as their formation mechanisms. Scaling laws, which attempt to link impacts at a variety of scales, are also introduced. Finally, we note the lack of extraterrestrial crater samples and how Science Concept 6 addresses this. Crater Types There are three distinct crater types: simple craters, complex craters, and multi-ring basins (Fig. 6.1). The type of crater produced in an impact is dependent upon the size, density, and speed of the impactor, as well as the strength and gravitational field of the target.

  • Gaia Hypothesis
    Gaia hypothesis The Gaia hypothesis /ˈɡaɪ.ə/, also known as the Gaia theory or the Gaia principle, proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self- regulating, complex system that helps to maintain and perpetuate the conditions for life on the planet. The hypothesis was formulated by the chemist James Lovelock[1] and co-developed by the microbiologist Lynn Margulis in the 1970s.[2] Lovelock named the idea after Gaia, the primordial goddess who personified the Earth in Greek mythology. In 2006, the Geological Society of London awarded Lovelock the Wollaston Medal in part for his work on the Gaia hypothesis.[3] The study of planetary habitability is Topics related to the hypothesis include how the biosphere and the partly based upon extrapolation from evolution of organisms affect the stability of global temperature, knowledge of the Earth's conditions, salinity of seawater, atmospheric oxygen levels, the maintenance of as the Earth is the only planet a hydrosphere of liquid water and other environmental variables that currently known to harbour life (The affect the habitability of Earth. Blue Marble, 1972 Apollo 17 photograph) The Gaia hypothesis was initially criticized for being teleological and against the principles of natural selection, but later refinements aligned the Gaia hypothesis with ideas from fields such as Earth system science, biogeochemistry and systems ecology.[4][5][6] Lovelock also once described the "geophysiology" of the Earth.[7] Even so, the Gaia hypothesis
