花岗岩

Topaz-bearing amazonite granite zone and topaz albite granite zone.

含黄玉天河石花岗岩以及黄玉钠长花岗岩。

The ore body occurred adjacent to the granite, thus it is inferred that mineralization stage is syngenetic or slightly later than emplacement of the granite, suggesting that mineralization of Mo, W, Pb, Zn and Ag was closely related to emplacement of the Yanshan period granites, and providing a new model for prospecting intrusive-related resource inside the volcanic rocks.

由于矿体赋存于岩体顶突部位的蚀变花岗岩中，预示成矿为花岗岩侵入的同期或稍后，即钼钨铅锌银成矿与燕山期花岗岩侵入活动密切相关，这对于火山岩内寻找与侵入岩有关的矿产提供了新的思路。

Based on the analysis of REE geochemical characteristics of different geologic rocks in Pangxidong silver deposit, the genesis of granitic wallrocks and the source of mineralised material are discussed. It indicates that Yingqiao granite belongs to syntectic granite of mixed crust mantle source.

分析了粤西廉江庞西垌银矿床不同地质体岩石稀土元素地球化学特征，对矿床围岩花岗岩的成因以及矿床成矿物质来源进行了讨论，认为英桥花岗岩体为壳幔混合源同熔花岗岩。

Recognition orA-type granite and I-type trondhjemite from available published results.

对区内花岗岩数据重新整理后，区分出碱性A型花岗岩和I型奥长花岗岩。

From about 206 Ma there occurred arc-continent collision accompanied by compressional contraction and shearing deformation of the arc crust and development of syn-collision granites. In the late Yanshanian epoch (138-73 Ma) post-orogenic extension came into action and resulted in the generation of A-type granites. During the Himalayan (65-15 Ma) intra-continental orogenic movement a large-scale strike-slip thrusting induced the intrusion of granites and development of pull-apart basins.

据此，再造了造山带的形成过程与演化历史：印支期的大规模俯冲造山作用(238～210 Ma)，形成义敦火山岩浆弧；大约自206 Ma始，发生弧-陆碰撞，伴随岛弧地壳挤压收缩和剪切变形，发育同碰撞花岗岩；进入燕山晚期(138～73 Ma)，岛弧碰撞造山带发生造山后伸展作用，形成A型花岗岩带；喜马拉雅期发生陆内造山作用(65～15 Ma)，岛弧碰撞造山带出现逆冲-推覆和大规模走滑平移，伴随喜马拉雅期花岗岩的侵位和拉分盆地的形成。

Based on the mapping of the granitic series and types, strontium isotopic trend surface analyses and isobaths of Moho surface, the deep-level sourced Yangtze series granitoids are mainly distributed in the eastern part of South China.

根据花岗岩系列和类型编图，华南地区浅源南岭系列花岗岩多產於中部和西部，深源长江系列花岗岩主要分佈在东部。

Jiaohe city is rich in 35 sorts of minerals resources: more than 10 billion steres of granite reserve and 3.8 billion polish granite makes her one of the four national great granite bases; about 2 billion tons of peat reserve is well known for its big amount and high quality; the prospect reserves of diatomaceous earth is over 300million tons; five spots of natural mineral water which have passed the state mineral department test produce 1200 tons everyday; other national and provincial excellent mineral sorts such as silicon, nickel, limestone, Erie stone, emerald, kyanite also rich in reserve.

已探明矿产35种，花岗岩储量超过100亿立方米，其中饰面花岗岩达38亿立方米，是全国四大花岗岩产地之一；泥炭资源储量近2亿吨；硅藻土远景储量3亿吨以上；通过国家地矿部鉴定的优质天然矿泉水5处；其它如硅石、镍、铜、钼、石灰石、伊利石、绿宝石、蓝晶石等属于国家和省内的优质矿种，也有丰富的储量。

The Early Devonian Shuangfengshan A-type granite is the oldest A-type granitic pluton ever found in Beishan, which provides important information for the researches on magmatic and tectonic evolution.

双峰山早泥盆世A型花岗岩为目前北山地区发现的最老的A型花岗岩，这对探讨古生代花岗岩成因类型及岩浆演化具有重要的意义

Two types of granites have been recognized, they are garnet granite and lueco granite.

依据矿物组成和地质特征，这些花岗岩可分为两种类型：大规模的石榴石花岗岩和小规模的淡色花岗岩。

The relationships between large igneous rock province, mantle plume and petroleum show that there is a low velocity-high conductive layer of mid-crust in the basin and this layer is the main source of oil and gas. Weathered granites and volcanic rocks are the best reservoir beds for hydrocarbon accumulation and the faults are the main migration pathway. It is suggested that granite and volcanic reservoirs be the future exploration targets.

通过研究花岗岩和火山岩油气藏的形成模式，指出大火成岩省、地幔柱与油气的关系表明盆地中地壳的低速－高导层可能是油气的主要来源，而花岗岩、火山岩的风化壳是油气成藏的最佳储集层，断裂则是其最主要的运移通道，花岗岩和火山岩油气藏将是未来勘探的重要目标。
