大型走滑断裂带,由于在水平方向的运动,导致两个区域发生扩张;另两个区域发生压缩。前者控制了拉分火山沉积盆地,形成了与火山作用同源的走滑—拉分张裂型侵入岩;后者控制了菱形地垒,形成了走滑—挤压隆起型花岗岩。这两类花岗岩同时产于同一走滑断裂带的不同部位,因其构造环境不相一致,在宏观上以被动就位和强力就位而有明显区分;在微观上以岩石化学等物质组分或趋近典型的张裂性花岗岩套,或趋近典型的挤压性花岗岩套,而泾渭分明。首次发现的这两类花岗岩并存的实例,为产于辽吉黑东部鸭绿江断裂带中的东宁老黑山—珲春农坪的走滑—拉分张裂型花岗岩套和浑江荒沟山走滑—挤压隆起型花岗岩套。它们形成的时代均属晚三叠世。
Large-scale strike-slip fault zones, due to horizontal motion, cause the two regions to expand and the other two regions to compress. The former controlled the pull-apart volcanic sedimentary basin and formed a strike-slip-pull-apart fractured intrusive rock with the same origin as the volcano. The latter controlled the rhombic barrier and formed a strike-slip-extruded uplift granite. These two types of granites are produced simultaneously in different parts of the same strike-slip fault zone. Because of their inconsistent tectonic environment, the two types of granites are distinguished in a macroscopic way with passive position and strong position. On the microscopic, Or approaching the typical cracked granite sets, or approaching the typical extruded granite sets, and quite different. The first co-existence of these two types of granites was found in the strike-slip-pull-apart granite sheaths and the Hunghuangou Mountain in Dongning Old Montenegro-Hunchun Nongping in the eastern Yalujiang fault zone of the Liaodong Blacks - Extruded uplift granite sleeve. They formed the era of Late Triassic.
