PETROGRAPHIC SUBDIVISION AND SEDIMENTARY ENVIRONMENTS OF THE CAMBRIAN CARBONATE ROCKS IN THE XIADONG AREA

1. Introduction The most developed area of Cambrian carbonate rocks in China is the Xiadong area in the west of Hubei Province, including Yichang, Zigui, Changyang and Yidu . In this area Cambrian carbonate rocks are well exposed and have various types of carbonate rock containing abundant fossils. One of the standard sections of Chinese Cambrian is also in this area. As early as in the early 20th century, a few foreign scholars, such as Pumpeuy, Richtuofeu, Willes, have made geologica…

SEDIMENTARY FACIES OF THE ZHARTAISHAN GROUP IN THE LANGSHAN-ZHARTAISHAN AREA, INNER MONGOLIA, CHINA

As an important tectono-stratigraphic unit on the northwestern margin of the North China Plate, the Zhartaishan Group of Mid-Proterozoic age is widely exposed in the Langshan-Zhartaishan area, Inner Mongolia (Fig. 1). The underlying basement of it is metamorphic rock series of the Upper Archaean Wulashan Group and the Lower Proterozoic Sertengshan Group. The overlying strata are of Paleozoic, Mesozoic and Cenozoic. The Zhartaishan Group is quite different both from the underlying met…

PALAEOZOIC TECTONIC PALAEOGEOGRAPHY OF THE CATHAYSIA IN EASTERN ZHEJIANG AND NORTHERN FUJIAN, CHINA

Based on the data about sedimentary facies and palaeogeography, this paper proves the existence of the Cathaysia (the part in eastern Zhejiang and northern Fujian, the same hereinafter) and makes a survey about its palaeogeography since Sinian Period. It also discusses the evolution of the tectonic environment of this region during Phanerozoic Eon, according to the features such as the composition of sandstones derived from the old land and alkalinity of volcanic rocks and so on. Continuous uplifting was maintained in Cathaysia during Sinian Period and Paleozoic Era, typically with no significant tectono-magmatic activity being observed. Its northwestern margin belongs to the type of passive continental margin during the middle and late phase of Caledonian Cycle. It showed the characteristics of a steady continent in late Paleozoic era, but was turned quickly into an active continental margin after the middle Jurassic period.

The term "Chihsia limestone" of Nanking Hills was primarily appliedby F.v.Richthofen to all those calcareous formations underlain by Devonianquartzite and overlain by Permian coal series which carries the characteristicbrachiopod Lyttonia.For more than 50 years,they were regarded as a unit,     

REPLY TO G. I. TEODOROVICH'S REVIEW OF “OIL,GAS, AND SOLID BITUMENS IN IGNEOUS AND METAMORPHIC ROCKS”

The reply points out that most of us are inclined to accept ideas if they agree with our own concepts and that we tend to accept them as facts. Kudryavtsev notes occurrences of hydrocarbons in basement rock of the U.S.S.R. which should be of interest to the petroleum geologist and which were unknown to Teodorovich. ‐‐W. D. Lowry.
