摘要:

河台金矿正在开采的2个矿床中,一组走向滑动构造是该区比较特征的找矿标志,普遍出现在矿体的中间和顶、底板,起着控制和破坏矿体的作用,而且该带的发育程度直接影响富矿脉的规模乃至存在。也就是说,在韧性剪切带型金矿中,矿体是受韧性剪切带的次一级脆性构造的控制;它与主构造面有一定的夹角,规模小、呈侧列形式出现在主构造带内;这一组走向滑动构造是韧性剪切带受多期构造活动的影响沿着Sc面理出现差异滑动而形成的。在构造面上局部出现的玻状岩是较晚期走向滑构造处于浅部瞬间应力快速释放时低温高压的产物,与是否控矿无关。

Abstract:

During the mining operating in two deposit of Hetai Gold Ore Field,ast rike-slip structure are characteristic indication on gold prospecting at this district,it generally occur on center and top and down of orebodies,and direct influence presence and scale of bonanzas.ln other words,in the ductile shear zone-gold deposit,orebodies controlled by the second-class britt lest ructure of ductile shear zone,it has a angle with main structure-see,and it occer side arrange of littler scale in main structure zone;the strike-slip structure formed by structure of many times activity,that it occur due to differential uplifting along Scmask.Pseudotachy lite on part of structure are that formed by strength fast released when low temperature and high pressure at later period and shallow level,and it not relation of form orebodies.

Key words: Hetai Gold Ore Field, ductile shear zone, divisional strike-slip structure, pseudotachylite brittle structure
