| 中文摘要: |
| 本文根据找矿矿物学,矿物学填图的基本原理和方法对漠滨贫硫化物型脉金矿床进行矿物学填图研究,同时对矿物包体、矿物组合及自然金成色作测定,编制了漠滨金矿区PD265-390中段矿物量分布图,反映出漠滨金矿有一定分带性.区域内此类矿床可分为不同亚类,为找矿预测提供了一定依据. |
| 英文摘要: |
| According to the fundamental principles and practice of prospecting mineralogy and chart plotting,a mineral chart plotting study is made on the sulphide-poor type gold vein deposit of mobin; characteratistics of the mineral fluids and inclusions and associations of minerals as well as the purity of natural gold are determined; distribution of minerals over the middle sector of Mobin Gold Deposit area PD 265-390 is mapped.It shows that there exists a certain zonality in Mobin Gold Deposit、Other conclusions are as follows:1.The favourable minerogenetic association is Py+Ars+Gl(Sp+Te),where natural gold has higher measure of pruity; and specific sulphide association formed at moderate temperature is related to pay ore.2.The character-isiies of the mineral inclusions show that the ore fluid is a KCL (NaCl)-H2O-S system.Hence the range of favourable minerogenetic temperature is ascertained.3.The study on the charting of ore technology has great significance in the management of the mine.4.In the sulphide of Mobin Gold Deposit,gold does not exist in the lattice,but is found in crevice,among crystals,or in mechanical mixture.5.Mobin gold vein type deposit may be further divided into three sub-types. |
