  • The Permian Calcareous Algae from Southeastern Anatolia
    THE PERMIAN CALCAREOUS ALGAE FROM SOUTHEASTERN ANATOLIA Utarit BİLGÜTAY Mineral Research and Exploration Institute of Turkey INTRODUCTION In the summer of the year 1958, I received some limestone samples which were collected near the village of Hazru (Diyarbakır - SE Anatolia) by R. H. Wagner1. During 1951 and 1954, this region had already been studied by Dr. Necip Tolun. According to the latter the entire stratigraphical column, which ranges here from the Devonian into the Quaternary, would be deposited in an environment of continual subsidence. With regard to the Paleozoic he states that the Carboniferous strata, which cover the Devonian, consist of bitumi- nous plant fossil containing sandstones. The Carboniferous is overlaid by Per- mian limestones from which he mentions: Mizzia yabei Karp. Mizzia sp. Gymnocodium Staffella sp. R. H. Wagner's samples were collected by him from these Permian lime- stones, about 50 m. above the top of the Carboniferous sandstone. Thin sec- tions prepared from these samples showed the presence of two distinct groups of green algae, which are the subject of the present study. SYSTEMATIC DESCRIPTIONS Class CHLOROPHYTA Subclass CHLOROPHYCEAE Order Siphonocladales Family DASTCLADACEAE Among the remains of Dasycladaceae, found in the Hazru region, there is an abundant representation of Mizzia. Furhermore, one fragment of Gyroporella has been found. No other examples of. Dasycladaceae have been encountered in the material from the Hazru region.

The section has been studied for palynology, ostracods and carbonate microfacies. Five microfacies types are defined for the carbonates of the Bellerophon Formation (Changhsingian) in this section. Ostracod assemblages from the upper Bellerophon Formation show a moderate to high diversity and mostly indi- cate normal marine conditions, with some samples from the upper Casera Razzo Member being dominated by eurytopic forms.

  • An Ancestral Tabulate Coral from the Ordos Basin, North China
    Zheng et al. Journal of Palaeogeography (2020) 9:26 https://doi.org/10.1186/s42501-020-00073-x Journal of Palaeogeography ORIGINAL ARTICLE Open Access Halysis Høeg, 1932 — an ancestral tabulate coral from the Ordos Basin, North China Li-Jing Zheng1,2,3, Hong-Xia Jiang4* , Ya-Sheng Wu1,2,5, Hong-Ping Bao6, Yue-Yang Zhang1,2,5, Jun-Feng Ren6 and Zheng-Liang Huang6 Abstract The problematic calcareous microfossil Halysis is abundant in the Middle Ordovician Darriwilian Stage of the western edge of the Ordos Basin, North China. The rich and well-preserved specimens of Halysis in this area facilitate detailed studies for its skeletal construction and tube microstructure. Halysis differs from calcified cyanobacteria and calcareous red and green algae in morphology, skeletal construction and microstructure, as well as reproduction mode. Halysis typically consists of multiple juxtaposed parallel tubes arranged in sheets (‘multiple- tube’ type) or is just composed of one tube (‘single-tube’ type). In ‘multiple-tube’ Halysis, tube fission by bifurcation results from the insertion of a microcrystalline wall at the center of a mother tube. This study demonstrates for the first time that the tube walls of Halysis have a laminofibrous (fibronormal) microstructure, composed of fibrous calcite perpendicular to wall surface, and recognizes the ‘single-tube’ type Halysis composed of one tube; in addition, for the first time, this study finds out that ‘multiple-tube’ Halysis develops buddings from the conjunction of two tubes and ‘single-tube’ Halysis shows wide-angle Y-shaped branchings. Based on these findings, this study further compares Halysis with tabulate corals.

  • Permocalculus Iagifuensis Sp. Nov.: a New Miocene Gymnocodiacean Alga from Papua New Guinea
    J. micropulueontol., 9 (2): 238-244, March 1991 Permocalculus iagifuensis sp. nov.: A new Miocene gymnocodiacean alga from Papua New Guinea M.D. SIMMONS & M.J. JOHNSTON Exploration Technology Branch, BP Research Centre, Chertsey Road, Sunbury-on-Thames, Middlesex, TW 16 7LN, United Kingdom. ABSTRACT -Pwmocu/c.u/usiagjfuensis, a new species of gymnocodiacean alga is described from the Miocene of the Darai Limestone Formation of Papua f!ew Guinea. The discovery of this species greatly extends the range of gymnocodiacean algae, which previously had only been confidently recorded from the Permian and Cretaceous. It also suggests an evolutionary link to the Recent genus Cu/uxuu~.u(order Nemalionales; family Chaetangiaceae), which is the only extant alga bearing ;I similarity to the Gymnocodiaceae. Alternatively, a closer relationship to the green udoteacean algae (e.g. Halimeda) is considered. The microfauna and other microfloraassociated with this new species are briefly described. INTRODUCTION STRATIGRAPHY AND MICROPALAEONTOLOGY. The Darai Limestone Formation (Late Oligocene-Middle/Late The Darai Limestone Formation (eg.

AL NAQIB U.S. GEOLOGICAL SURVEY PROFESSIONAL PAPER 560-G A review of the geology of southwestern Iraq as shown on USGS Miscellaneous Geologic Investigations Map 1-2 ^O A, "Geologic Map of the Arabian Peninsula" UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON : 1967 DEPARTMENT OF THE INTERIOR DONALD PAUL HODEL, Secretary U.S. GEOLOGICAL SURVEY Dallas L. Peck, Director First printing 1967 Second printing 1985 For sale by the Distribution Branch, U.S. Geological Survey 604 South Pickett Street, Alexandria, VA 22304 FOREWORD This volume, "The Geology of the Arabian Peninsula," is a logical consequence of the geographic and geologic mapping project of the Arabian Peninsula, a cooperative venture between the Kingdom of Saudi Arabia and the Government of the United States. The Arabian- American Oil Co. and the U.S. Geological Survey did the fieldwork within the Kingdom of Saudi Arabia, and, with the approval of the go'vernnients of neighboring countries, a number of other oil companies contributed additional mapping to complete the coverage of the whole of the Arabian Peninsula. So far as we are aware, this is a unique experiment in geological cooperation among several governments, petroleum companies, and individuals. The plan for a cooperative mapping project was originally conceived in July 1953 by the late William E. Wrather, then Director of the U.S. Geological Survey, the late James Terry Duce, then Vice President of Aramco, and the late E. L. deGolyer. George Wadsworth, then U.S.
