POSITION OF ARSENIC MINERALS IN THE METALLOGENIC SERIES.

INTRODUCTION. A great deal of attention has recently been paid to problems pertaining to the biological and geological history of Asia and in no part of the continent has a knowledge of its fauna and structure both past and present been advanced more widely during the past decade than in that comprising China and Mongolia. This fortunate circumstance has not been brought about     

PROCEEDINGS OF THE EIGHTH GENERAL MEETING HELD IN PEKING,JULY 25th. & 26th.,1924.

The eighth general meeting of the Geological Society of China was the first meeting in the year 1924, following the Annual Meeting. It was arranged in two evenings as follows.     

粤东汕尾岬间海滩剖面月内日变化过程特征分析

运用经验特征函数方法，结合逐日实测波浪、潮汐及剖面冲淤变化资料，对粤东汕尾寮咀口岬间海滩重复测量的剖面数据加以分析。结果表明，海滩的月内日变化过程可客观地通过对应于2个最大特征值的2个经验特征函数来描述：1）第1经验特征函数表征主要的海滩剖面过程，称为要模式，它是响应叠加在月潮汐周期性循环上的波浪动力作用；2）第2经验特征函数反映了海滩剖面快速变化过程，称为次要模式，它又可分为前滨上部过程、冲淤过渡段及后演上部过程。     

煤层裂缝的声波扫描成像测量

煤层中的裂缝是煤层气勘探和开发的重要参数。利用声波扫描图像可以观察出煤层中的裂缝发育程度、裂缝的产状,并可以分析出裂缝产生的力学性质,给煤层气储层的综合评价提供依据。
