PROGRESS OF GEOLOGICAL STUDIES AT THE ACADEMY OF SCIENCES OF THE U.S.S.R.

Progress report deals with: 1) Geochronology — potassium-argon — principally Precambrian. Gives dates on Precambrian of Baltic Shield including eastern Sweden, Northeastern Norway, Finland, Karelia, and Kola Peninsula. Gives a correlation of the Precambrian for the entire European U.S.S.R. 2) Depth and origin of magmatic ore deposits using reconstructed erosion surfaces for the major periods of mineralization. The depth zones of ore formation of American and European theories is questioned. 3) Tectonic mapping in crustal studies. And in this conjunction 4) Bathy-metric map of the Pacific has been prepared, conspicuous features are major tectonic and volcanic forms of the ocean bottom, as well as minor detail. Brief mention is made of ore deposits from the ocean. 5) “Weathering Crust” studies of subaerial weathering erosion and deposition, mainly of ancient crusts. 6) Study on the origin and distribution of “agricultural areas”, mainly phosphates. 7) Compilation of a Manual of Minerals now underway.--M.A. Klugman.     

GEOLOGICAL STUDY OF THE DEPOSITS OF THE SANGKANHO BASIN.

This paper offers a preliminary statement of the results of investigations carried out in the South Sangkanho basin, in the mountains some 80 miles to the NW of Peking. Important fossiliferous deposits found in this area throw light on the conditions ruling in N. China during the transition from Pliocene     

THE BEGINNING OF THE USING OF ZINC IN CHINA.

In my work, Lapidarium Sinicum, the chapter on brass is speciallydevoted to this inquiry. Recently Dr. Read of the U. S. Bureau of Mineswrote to Dr. Ting, suggesting the question whether "The knowledge ofzinc-smelting in India is previous to that developed in China." Therefore

THE PLEISTOCENE VOLCANOES OF THE SANGKANHO.

INTRODUCTION Looking east across the Yüho from the higher ground around Tatungfu, the eye is caught by a dome-shaped hill on the horizon some twenty miles away. The existence of volcanoes in that direction had already been brought

ON THE AGE OF THE TAIYUAN SERIES OF NORTH CHINA.

Regarding the age of the marine beds in the lower part of the coalbearing series of North China, palaeontologists differ widely in opinion. It has been assigned to various horizons ranging from Viseen up to Upper Carboniferous by former investigators, such as Girty, Loczy, Frech,

大青山山前断裂带中、晚全新世活动的发现

大青山山前断裂带位于大青山南麓,为河套断裂系的重要组成部分。该断裂带控制大青山山体的抬升和呼和断陷的形成,地貌特征十分明显,第四纪断层十分发育。大青山山前断裂带第四纪强烈活动,但有关全新世活动的确凿证据未能肯定,亦未见有报道。近年来,我们在包头东河区至沙尔沁一带,发现含全新世文化层的坡、洪积地层多处被错断,证实大青山山前断裂带中、晚全新世活动仍较显著,这对研究河套地区可能存在古地震遗迹提供了重要的线索。     

THE MESOZOIC STRATIGRAPHY OF THE YANGTZE GORGES.

The geology of the Yangtze Gorges has been studied by many eminent geologists, among whom Pumpelly, Abendanon, Willis, Blackwelder and Noda are specially to be mentioned. These studies made known the     

THE GENESIS OF THE MANGANESE DEPOSITS OF CHINHSIEN, KWANGTUNG.

INTRODUCTION Manganese deposits are the most important mineral resources of Chin-hsien. To these manganese fields the author paid a visit of some days in April, 1929. The present paper is a summary of the manganese deposits of     

NOTES ON THE STRATIGRAPHY OF THE SPIRIFER TINGI BEDS OF KUEITING.

The corals described by Dr. Grabau in the preceding pages came from a place 350 m W. of the village of Machiat(?)un, which is situated 11.7 kilometers east of the district city of Kueiting in Kweichow province. The specimens from locality T107 were found in situ and those from T107a were collected from the slabs used for pavement right besides locality T107.

THE BASE OF THE PALAEOZOIC IN SHANSI.METAMORPHISM AND CYCLES.

I had recently an opportunity for observing, along the western border of the northern Hoshan (Central Shansi), at the base of the Palaeozoic, a particularly clear section, in which several interesting features seem to be worth mentioning. This section, illustrated in the text-figure 1, was taken at the entrance     

多元信息分析技术在460地区深层构造研究及找矿中的应用

在华北地台北缘中新生代火山岩发育区,发现大型铀钼矿床,其外围被第四系广泛覆盖。为了进一步扩大找矿,我们采用了以遥感图象、地质图件、航磁、航放资料为基础信息的多元信息计算机综合分析技术。通过已知成矿模式的建立,对与成矿有关的地质体与基础信息源之间的相关性研究,对这些相关信息在图像处理系统中进行的组合显示分析,从而确立了各类地质体及控矿地质要素复合集聚区的多参数影像模型;查明了它们的空间分布规律;圈出了5个主体火山机构;发现了大规模蚀变带及其与铀矿化异常之间的空间相关关系。据此编制出反映该区成矿地质环境的第四系覆盖层下深部地质构造影像图及成矿远景区影像图,在某一远景区内用航空彩色红外图像及侧视雷达图像进行解译,圈定了5个隐伏次火山岩体。经钻探验证了它们的存在并发现工业铀矿化。这一切都为已知矿区的外围扩大找矿工作起了指导作用。
