Massive phosphorus-rich deposits in E Yunnan were formed by weathering enrichment, their primary ore-bearing beds belong to the Meishucun Formation of Lower Cambrian. The internal factors forming these deposits are mainly the lithofacies, lithologies and phosphoric abundance of the primary orebearing beds. The primary ore beds of the weathering enriched phosphorus ores with middle—, and large-scales which have been ascertained are all the dolomitic phosphorite. The external factors of the first importance for minera-lization require a hydrogeologic condition promoting the reservoir, permeation and migration of the sueface filtration and underground circulation water. The depths of weathering enrichment were restricted above the water table. The gentle topography, gentle occurrence of primary rock and consequent slope are found in mining areas, and the covering strata consist of the dolomitite or quartz sandstone with a thickness of less than 30 m. The quantitative indexes discriminating the weathering enriched phosphorus ores in E Yunnan are mostly based on the chemical components and their relative ratioes. The authors use the carbonate content(esp. the CO_2 content)to demarcate the weathering intensity of phosphorus ores. Changes in MgO, CO_2/P_2O_5, CO_2+MgO/P_2 O_5 and CaO/P_2O_5 show approximate or consistent tendency with the CO_2 content. The phosphorus concentrates of high quality can be obtained from weathering phosphorus ores through easy and ripe process flow——cleaning desliming. Because of the exploratory methods for the weathering phosphorus deposits having its own uniqueness, men should pay equal attention to understanding both of the deposit itself and its natural geographic factors for enrichment, and understanding both of the surface and deep part in deposit during exploration.

滇东地区的富磷矿床,系风化富集形成,原生含矿层为下寒武统梅树村组。富集成矿的内在因素主要是原生含矿层的岩相、岩性、含磷丰度,区内的含磷层均为白云质磷块岩;外在因素首先是具备地表渗流水和地下环流水的储集、渗透、运移的条件,风化富集深度限于地下潜水面以上。富磷矿床处于地形平缓区,多系顺向坡,岩层倾斜平缓,盖层为白云岩或石英砂岩,其厚度一般小于30米。判别本区风化富集磷矿的定量指标主要依据化学组分及其相关比值。笔者采用碳酸盐(特别是CO_2)含量来标定磷矿石的风化强度。风化磷矿石经简易的工艺流程(擦洗脱泥)即可获得优质精矿。磷矿风化矿的勘查方法有其独特性,研究矿床本身的同时要研究其富集的自然地理因素,地表与深部地质研究并重。

Synthetic geophysical operations in 1: 50000 geological surveying include surveying synthetic sections and rock (stratum) magnetism, and processing data of gravitational and magnetic fields. Based on the characteristics of gravitational and magnetic fields,geological provinces may be divided,division marks of geological bodies and structures can be defined, deep geological sketch can be completed through confirming the results of charting and deducing deep geological bodies and structures. The geophisical operations make the geological working more precise and provide more basis for deep geological studies.

Based on diatectical materialism the paper discusses some aspects of the epistmology and methodology in the current igneous petrology. It is emphasized that the maxist principles on the ideas of the interaction and interdependeney. System science and dissipative structure have also been applied to the current igneous petrology. This paper philosophically discusses physical processess of magmatism, Mantle—magma—C—H—O system, open magma system, magmatism—plate tectonics—super—mantle plume—global mineralization....

本文以现代火成岩岩石学的概念为出发点,从哲学的角度讨论了现代火成岩岩石学的某些前沿课题。对岩浆作用的全面认识,不仅要研究其化学过程,还必须从物理过程去探索;地幔—岩浆—C—H一O系统的研究是深部地质研究的一个侧面,深部地质过程是地表及浅部地质现象的动力来源;超地幔热柱是板块运动和大规模岩浆活动的起因,大规模的岩浆活动及板块运动是超地幔热柱在地表或地壳浅部的直接表现;开放的岩浆体系的提出,丰富了现代火成岩岩石学的内容。
