A given tectonic force may be resolved into two parts: homogeneous stress and differential stress. Homogeneous stress refers to isotopic pressure,which is superimposed on the original pressure and affects the equilibrium of various chemical reactions. It is also a factor that influences petrogenesis,metallogenesis and metamorphism.

The Dabie Mountains are unique among ultrahigh pressure metamorphic terranes in having the most profound post collisional plutonism The Mesozoic shoshonitic and calc alkaline intrusive rocks can be divided into three groups with different isotopic ages, rock assemblages and chemical features Group I consists of late Triassic (~ 210 Ma) mafic monzodiorites It could have been generated by partial melting of enriched subcontinental lithosphere mantle due to slab breakoff Group II consists ma...

第 I组，主要由晚三叠世（约210 Ma）二长闪长岩辉长岩体组成，它可能是在板片断离过程中富集的大陆岩石圈地幔部分熔融的产物；第I I组，由中侏罗世－早白垩世（160～120 Ma）的角闪石英二长岩、黑云母二长花岗岩和正长花岗岩组成，主要是由幔源岩浆的分离结晶与地壳混染共同作用的产物；第II I组，以白垩纪（125～95 Ma）的花岗岩和花岗斑岩为代表，是在热穹窿作用过程中大别杂岩深熔作用和高度演化的产物。

Based on field survey and microstructure analysis the author considered that Yiwulvshan is a Cretaceous metamorphic core complex, and pointed out the time of Yiwulvshan granite is not early Yanshanian by the comprehensive analysis of the regional structures and isotopic dating, but a late Yanshanian granite.

在此基础上，作者经过野外宏观观测和室内显微分析，基本厘定医巫闾山是一个白垩纪形成的变质核杂岩。根据区域构造演化综合分析及同位素年龄测定，认为医巫闾山花岗岩体时代并非前人所定的早燕山期，而是晚燕山期岩体。

Taking the Late Mesozoic basic-intermediate dike swarms from this area as the main object, we have studied their Petrology, Geochemistry and Isotopic Chronology, and discussed the property of their magmatic source, tectonic setting and origin as well. The significant conclusions acquired are as follows: 1, The Late Mesozoic dike from the coastland of Fujian Province appears as clusters, intruding into the Late Mesozoic granite or volcanic rocks, and the lithologies are diabase, hornblende diabase and quartz-diorite etc, mainly diabase. The mode of their occurrence is mainly precipitous and they tend towards NE, approximately EW or NNE. The dike swarms did not suffer metamorphose or distortion, holding the stress state as the dike formed.

本论文以该地区晚中生代中–基性岩墙群为主要对象，研究了它们的岩石学、地球化学及同位素年代学等，对岩浆源区的性质、构造环境、成因等进行了讨论，获得以下重要认识： 1、福建沿海地区晚中生代中–基性岩墙成群产出，侵入到晚中生代花岗岩及火山岩中，岩性有辉绿岩、角闪辉绿岩和石英闪长岩等，以辉绿岩类为主，产状较陡，北东、近东西及北北东走向，大多未发生变质或变形，保持了岩墙形成时的应力状态。

However, a quasigroup which is isotopic to a group need not be a group.
