SOME OBSERVATIONS ON THE OLDEST FORMATIONS IN THE PROVINCE OF SHANSI.

The western and north-eastern parts of Shansi Province are districts of typical development of the oldest Pre-Palaeozoic formations. In western Shans these formations are well exposed in the territory midway between the Taiyuan plain and the Yellow River and are bordered on almost all sides by the so-called Shansi Formation of late Palaeozoic age. Near the margin the area of oldest     

全國地質院校情况簡介

一在國家過渡時期總路綫的光輝照耀下,地質幹部的培養工作是配合祖國工業化的重要任務之一。为了早日過渡到社會主義社會,就必須有足够幹部去担任資源勘探和工程地質勘测工作。因此,在1952-1953年先後成立了北京和東北兩個地質学院和六所中等技術學校;除在北京、東北兩個學院開     

鑽孔定盤測斜仪的構造及其应用方法

目前我国在測量鑽孔弯曲的方法上,多使用鲍良可夫、2型以及氢氟酸等測斜仪。前两种由于以磁針作用測量鑽孔方位角,故只适用于无磁性感扰的鑽孔。而后一种虽能用于有磁性感扰的鑽孔,但其誤差大,操作复杂化费时間長,在使用上还不是很理想的。为此,我們試制了定盤測斜仪,它的构造和作     

湖北陽新赤马山几种石灰角礫岩

1952年五、六月間,筆者調查湖北陽新、大冶兩縣銅礦,曾在陽新縣西北30公里的赤馬山工作了四十多天。區內地層,除了志留紀的富池頁岩和一大片閃長岩的露頭外,其餘全是石炭紀的黄龍灰岩和船山灰岩,以及下二疊紀的棲霞灰岩。在這些石灰岩裏     

地質條件在鎢礦脈狀礦床礦量分級計算中的重要性

礦量分级計算法,是蘇聯地質科學中一個先進的工作方法。這一方法具體而生動地運用了量的變化引起質的變化,這一馬克思列寧主义的科學原理,用一定的工作量去規定了各級礦量的質量要求,使我們能够有把握地、有权據地利用各級礦量,作為生產設計和勘探设计的依據。我們知道,资產階級的礦量計算法,都是用一些抽象的概括的名詞來說明礦量的可靠性,例如(?)可能     

ON THE OCCURRENCE OF THE MANTICOCERAS FAUNA IN CENTRAL HUNAN

INTRODUCTION Mr.K.K.Chao (赵金科) of the National University of Peking hasrecently brought back several specimens of the Goniatites from the ShaitienchiaoSeries of Huaishuichuang (槐树荘) near T'iaomachien (跳马涧),Changsha     

GRAPTOLITE-BEARING STRATA OF CHINA

During the past ten years graptolite-bearing strata were repeatedly discovered in various localities by the members of the Geological Survey of China, and by the Expedition of the National Peking University and the collections~1 of graptolites were obtained from different horizons (Tremadocian-Valentian).
