| 中文摘要: |
| 论文由小秦岭金矿成因简述、主要控矿因素及成矿模式等三部分内容组成。本文从回顾各成因观点主要依据入手,提出问题,并系统论述小秦岭金矿主要控矿因素。试图通过研究区域地层、构造和晚燕山期岩浆活动等对金矿化形成的控制作用,讨论矿质的来源、运移方向、滞留、沉出的空间与方式等成因问题。在此基础上用文字表述和图示的方式概括了小秦岭金矿的成矿模式。 |
| 英文摘要: |
| Xiaoqinling Area is a main producer of gold in China.Attention has been paid to genesis of deposits in the area and many genetic models are proposed.Being confined to different genetic views ore-controlling factors can not be analysed objectively.Main facts supporting the models are reviewed and questions are presented in this paper.The authors make a systematic exponent of ore-controlling factors and an inquire into the control and influnee of regional stratigraphy,tectonics and late Yianshanian magmatism on gold mineralization.Aspects of resources and transportation of ore material,space for ore fluid to stay and the precipitation way of ore material are discussed.And a new model (see to Fig. 9)is worked out. |
