Abstracts of 2011 PGFS Co-sponsored by: Table of Contents Welcome ………………2 General Information ………………3 Overall Schedule ………………4 Program of Oral Session on Saturday ………………5 Program of Oral Session on Sunday ………………7 Program of Poster Session ………………9 Abstracts of Oral Session ………………O1 Abstracts of Poster Session ………………P1 Welcome Message from Organizing Committee Chair Needless to say, this is a special year for us. Disastrous earthquake in March caused uncountable influences on not only our economy, but also research activity. Fortunately none of PERC staffs suffered injuries, however, some laboratory equipment were severely damaged. Consequently we were forced to reschedule the plan of this symposium. Nevertheless, we managed to open this symposium at last by many kind helps from the world. It is our great pleasure to have 78 participants from 10 countries (excluding on-site registration) meeting for this symposium and presenting a variety of topics such as most recent achievements of planetary exploration and fundamental studies of terrestrial geology. We hope that every participant enjoys this symposium as much as we do. Noriyuki Namiki Chair of Organizing Committee, 2011 PERC Planetary Geology Field Symposium ~“~“~“~“~ “~“~ “~“~ “~“~ “~“~ “~“~ “~“~ Message from Scientific Committee Chair 2011 PERC Planetary Geology Field Symposium is the first attempt in Asia to bring together scientists and engineers involved in various branches of planetary and terrestrial geosciences. Here in this abstract book, you will find papers on surface and internal processes of terrestrial planets, asteroids and icy satellites, papers on terrestrial analogs and biology, and exploration technologies such as rovers and onboard instruments. Effective interactions of planetary and terrestrial geoscientists and engineers have increasingly become important for understanding evolution of surfaces and interiors of planetary bodies. Thus the symposium is intended to foster active discussion among such diverse disciplines, hoping to provide the gained insights to the specific areas.

  • Dr. Victor Rebrik the History of World Civilization. 1 Vol. 1 the Volume Is Dedicated to the Memory of the Russian Orientalist I.M
    Dr. Victor Rebrik The history of world civilization. 1 Vol. 1 The volume is dedicated to the memory of the Russian orientalist I.M. Diakonoff (1914- 1999). In the introduction to vol. 1 the author explains his new conception of world history. World history is divided into two parts-primitive society and the history of civilization; only the second of these has a strictly defined development. The history of civilization is divided into 21 periods of 250 years each, beginning from 3050 B.C.E. The author has discovered the historic cycle of 2250 years, which is divided into nine periods of 250 years each; these periods are distributeed in the relation 4: 5 (1000: 1250 years), which forms the "antiquity" and "middle Ages" of each cycle. The "retardation law", according to which a civilization begins in the New World 3000 years later than in the Old World, allows a true consideration of the history of pre-columbian civilizations, which were at the level of the ancient oriental civilizations. The four social-economic formations (early class, slave owners’, feudal and capitalist) are considered by the author; they are not the cause, but the consequence of the historic development. History develops in the spiritual sphere as well, its true aim is to return humanity to the Absolute. Then the author gives a brief outline of pre-civilization (in Egypt, Mesopotamia, Mesoamerica and Southern America), which corresponds to the late stone Age. The first volume is dedicated to the first cycle of history, which is called "archaic" and roughly corresponds to the Bronze Age (in the Old World).

    JOURNAL OF GEOPHYSICAL RESEARCH: PLANETS, VOL. 118, 1013–1032, doi:10.1029/2012JE004174, 2013 Mercury’s hollows: Constraints on formation and composition from analysis of geological setting and spectral reflectance David T. Blewett,1 William M. Vaughan,2 Zhiyong Xiao,3,4 Nancy L. Chabot,1 Brett W. Denevi,1 Carolyn M. Ernst,1 Jörn Helbert,5 Mario D’Amore,5 Alessandro Maturilli,5 James W. Head,2 and Sean C. Solomon6,7 Received 2 July 2012; revised 10 October 2012; accepted 26 November 2012; published 22 May 2013. [1] Landforms unique to Mercury, hollows are shallow, flat-floored irregular depressions notable for their relatively high reflectance and characteristic color. Here we document the range of geological settings in which hollows occur. Most are associated with impact structures (simple bowl-shaped craters to multiring basins, and ranging from Kuiperian to Calorian in age). Hollows are found in the low-reflectance material global color unit and in low-reflectance blue plains, but they appear to be absent from high-reflectance red plains. Hollows may occur preferentially on equator- or hot-pole-facing slopes, implying that their formation is linked to solar heating. Evidence suggests that hollows form because of loss of volatile material. We describe hypotheses for the origin of the volatiles and for how such loss proceeds. Intense space weathering and solar heating are likely contributors to the loss of volatiles; contact heating by melts could promote the formation of hollows in some locations. Lunar Ina-type depressions differ from hollows on Mercury in a number of characteristics, so it is unclear if they represent a good analog.
