岩浆岩定位机制的新类型——螺旋上冲

A new type of magmatic rock orientation mechanism:screw upwelling

通过对望天龙含铬超基性岩、凤凰山含铜(铁)花岗闪长岩-石英二长闪长岩、以及老君山南温河花岗岩等多个岩体构造资料的再分析,确认该类岩体的定位机制不同于当前国内外所提出的:穹窿、底辟、气球膨胀、岩墙扩展,顶蚀、火口陷落和三元复合机制。显示为一种新的类型:即由岩浆于岩浆房产生螺旋运动携带着巨大的动能呈螺旋上冲扩展而侵位到上地壳乃至表壳层中,可简称其为"螺旋上冲"定位机制。

Through the reanalysis of the Wangtianlong ultrabasic rock with chromium, Fenghuangshan granodiorit- quartz monzodirite with copper （ iron）, Laojunshan southern Wenhe granite and other information, confirmed that rock body is different from the current proposed at home and abroad dome, diaper, balloon expansion, dike expansion, stopping, cauldron subsidence and compound ternary mechanism, showing as a new type. The magma in the magmatic chamber formed a screw motion with enormous energy, showing screw upwelling expansion and intrusived upto the upper earth crust and super crustal layer, so, it is named as ＂screw upwelling＂ orientation mechanism.
