In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

本文重点以老厂矿田中的接触带锡铜矿床和脉状矿床为研究对象，采用化学分析、ICP-MS、X射线粉晶衍射分析、电子探针等测试手段，对本区与成矿相关的基性-超基性火山岩、花岗岩、夕卡岩、电气石-石榴石等进行了系统的地质地球化学研究，研究表明：个旧矿区中三叠纪个旧组地层中的火山岩为钙碱性玄武岩-拉斑玄武岩系列，岩石为辉石-角闪石-长石-绿泥石-金云母组合；本区的花岗岩为过铝质花岗岩，主要与燕山期碰撞造山作用有关，锡多金属成矿与形成时代最晚、分异较好的花岗岩关系密切；本区夕卡岩中的有用共生组份随着夕卡岩类型及其矿物组合的不同具有明显的分带性。

According to logging results of 167 boreholes and chemical analyses of 24 369 samples as well as characteristics of element distribution at 4000 m, 3950 m and 3900 m levels, the deposit is characterized by alteration, mineralization and element geochemistry of the porphyry. Alteration and mineralization are spatially and temporally related to the augen quartz phenocryst-bearing hornblende-quartz diorite porphyrite (J3δομ).

根据167个勘探钻孔编录和化学分析（24369件化学分析样品）资料，以及对海拔4000m、3950m、3900m水平面的Cu、Au、Ag、Mo、Mn、Pb、Zn、W、K、Na、Ca、Rb元素分布规律的分析，显示矿体具有斑岩型矿床的蚀变、矿化以及元素地球化学特征，主要矿化和围岩蚀变在时间上和空间上均与含眼球状石英斑晶的角闪石英闪长玢岩(J3δομ)有关。

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。

Anyolite is the name frequently applied to all gemrocks that consist largely of massive apple-green zoisite plus ruby-red corundum ( i.e., medium or relatively low grade ruby)± macroscopic hornblende.

Anyolite ，该名称是一个经常惯用的宝石名称，准确描述了其组成是又大块的苹果绿黝帘石，并伴随红色刚玉（中度或者低级别的红宝石）以及肉眼可观察到的角闪石。

In terms of structural characteristics and geochemistry of the granites in conjunction with previous studies, we interpret that the garnet-bearing gneissic granite was formed during the collision between the Tianshuihai terrane and the Southern Kunlun terrane following the closure of a branch of the paleo-Tethyan ocean along the Mazha-Kangxiwa suture zone, the block hornblende-bearing granite was formed during post-orogenic extension. On the other hand, the granites of ca.

根据两个岩体的构造特征，结合前人的研究及地球化学特征，表明含石榴子石片麻状花岗岩形成于同碰撞造山时期，是甜水海地体与西昆仑南带晚古生代岛弧沿麻扎-康西瓦缝合带碰撞峰期的产物，代表了沿麻扎-康西瓦分布的古特提斯洋一个分支的闭合，而228 Ma块状含角闪石花岗岩形成于碰撞造山后的伸展背景。220～190 Ma持续发育的花岗岩是南昆仑地体拼合到北昆仑地体之后在其南部形成的新的深成岩浆弧带。

Such textures suggest the development of reaction:① Gt〓+Cpx〓+Qz→Opx〓+Pl〓 and ② Gt〓+Cpx〓+Qz+H〓O→ Hb〓+Pl〓 Reaction ② is the first discovery in the granulite series in our country, the later cooling stage of M〓 was recognized by growth of yellowish green hornblende of amphibole facies at the expense of various pyroxenes.

在麻粒岩系中发现同一石榴石晶体边缘不同部位同时发生Gt+Cpx+Qz＝2Opx+pl和5Gt+5Qz+2H〓O＝2Hb+Pl等典型的降压反应，这一现象在国内麻粒岩系中也属首次发现。并通过这些特征变质反应实验资料的深入研究，确定了它们的平衡条件及所代表的P-T演化意义。
