山柞镇旬地区盆地体制与金属成矿关系

The ralationship to basin constructure system with metallgenic in Shan(yang)-Zha(shui)-Zhen(an)-Xun(yang)area

摘要: 山柞镇旬地区现今构造格架是在后泥盆纪秦岭造山过程中奠定的,秦岭北鄂尔多斯板块左行旋转,扬子地块向北挤压及左行旋转,使秦岭微板块沿商丹和勉略两条长寿深大断裂发生大规模的左行走滑,主要形成EW向的柞(水)-山(阳)断裂,镇(安)-板(岩镇)大断裂;伴随佛坪地块的隆滑而产生的NW-NWW向公(馆)-白(河)断裂、旬河断裂,形成和控制了山柞、旬阳热水盆地和镇安-青山隆起以及沿旬河的裂陷,控制了柞山镇旬地区金属成矿带的分布和最终矿床的形成.

Abstract: Its structure sketch is settled by the Qinling Belt-genetic process of off-Devinian in Zha(shui)-Shan(yang)-Zhen(an)-Xun(yang)area.The kenetic mechnism is that Erdos plate left-circumrotated and Yangtz plate left-circumrotated with extrusion to north makes Qinling plate left-slided along Shang(xian)-Dan(feng)and Mian(xian)-Lue(yang)longevity faults,and forms EW tend towards Zha(shui)-Shan(yang)fault and Zhen(an)-Ban(yanzhen)fault,forms NW-NWW tend towards Gong(guang)-Bai(he)fault and Xunhe fault by Foping hunch-sliding.Those faults control Zha(shui)-Shan(yang),Xunyang hydrothem or basis and Zhen'an-Qingshan hunch and Xunhe crack,as well as the dist rbutions of metal deposits in Zha(shui)-Shan(yang)-Zhen(an)-Xun(yang) area.
