一、绪言1.研究目的及经过随着科学技术的进步,特别是无线电尖端技术的飞跃发展,国家对作为半导体原料的锗矿资源需要愈益迫切;煤中锗为目前世界上锗的重要来源之一,且具有最大的储量。因此,对其进行系统的研究,无论在理论上或实际上都有重大的意义。本文是在对我国东部某些合锗煤进行研究的基础上,对煤中锗的地球化学特点进行讨论,试图探索煤中锗的形成条件及分布特征,以便提供可作为普查合锗煤的某些找矿标志。
I. INTRODUCTION 1. Research Objectives and As the rapid development of science and technology, especially the rapid development of wireless cutting-edge technologies, the country is in urgent need of germanium resources as semiconductor raw materials; germanium in coal is an important source of germanium in the world One, and has the largest reserves. Therefore, the systematic research on it has great significance both in theory and in practice. Based on the study of some germanium coals in eastern part of our country, this paper discusses the geochemical characteristics of germanium in coal and attempts to explore the formation conditions and distribution characteristics of germanium in coal in order to provide a Some prospecting signs.
