The depth of emplacement of this granite body obtained by the hornblende geobarometer is up to 24.5 km.

摘 要：锆石U-Pb年龄表明鄂东月山岩体是一个古老花岗岩经后期重熔并于燕山中期(139Ma)侵入的花岗岩体，角闪石压力计得出侵位深度达24.5km。

Finally, by studying on using saw blades with different matrices cutting different stones, a basic compatibility rule about matrices and stones was concluded, say, when cutting a hard, high quartz and high alkalifeldspar content and strong bonded stone, a high impact strength and low wear-resistance matrix should be chosen; otherwise, when cutting a soft, low quartz or no quartz content and weak bonded stone, a high bending strength, low impact strength and high wear-resistance matrix should be chosen.

最后，通过对不同性能结合剂的锯片切割不同石材的切削寿命和磨损状态分析，得出了锯片结合剂性能与岩石性质之间的一般性匹配原则：即对于坚硬的、高石英含量的花岗岩，宜选用高强度、高冲击韧性、低耐磨性和对金刚石具有良好粘结性能的结合剂；对于低硬度、无石英或低石英含量的易切削花岗岩，宜选用高强度、高耐磨性和低冲击韧性的结合剂。

East of the deposit is the famous Lincang-Menghai batholithic granite formed during Varisn to Indo-Chinese epoch which has a north-south direction of strike, west is Lancang grouup metamorphic rock.

矿体产在花岗岩与变质岩的构造破碎接触带中，成矿与花岗岩浆活动及大气降水所形成的流体作用有关。

The massive sulphide, lead-zinc, iron, copper deposits of the former and the porphyry copper-molybdenum deposits of the latter are the main ore types in the region.3. The conclusions drawn through the research on the Re-Os isotopic geochronology of the Chilu Mo deposit are as follows:(1) the model age of the Chilu Mo ore deposit is 105.6Ma, closely to the 87Sr/86S isochrone age of the porphyric granite, adamellite. So they are closely correlated in the genesis, and both are the production of magmatic evolution of the late Yanshan.

Cu、Mo、Pb、Zn、Au为区内优势矿种。3、对赤路钼矿床的Re—Os同位素年代学研究得出如下结论：(1)赤路钼矿的矿化模式年龄为105.6Ma，与似斑状花岗岩、二长花岗岩等的87Sr/86Sr等时线年龄115±4Ma较接近，表明二者在成因上密切相关，同属燕山晚期岩浆演化的产物；(2)赤路钼矿床具有辉钼矿中Re、Os含量偏低，低87Sr/86Sr初始值和硫同位素组成接近陨石硫等特点，表明其为成矿物质来源于地壳深部，且为斑岩型钼矿床。

All of these three metallogenetic series can be merged as one group of metallogenetic series, i.

其中，湘桂成矿单元有：Ⅰ-燕山早期中酸性花岗岩类有关的W、Sn、Sb、Pb、Zn矿床成矿系列：Ⅱ-燕山晚期酸性花岗岩类有关的W、Sn矿床成矿系列：Ⅲ-燕山早期构造-热事件有关的Au、Ag、Cu、Pb、Zn矿床成矿系列。

According to the research of the paper, the "migmatite" of the Sizishan Formation, Xingdong Group distributed in northern Xiao Hinggan Mountains should be a suit of gneissic quartz monzonitegranite intrusions. Their whole rockmineral Rb-Sr isochronic dating is (482±19) Ma, indicating that an Caledonian magmatic events existed in the giant granitic belt of the Xiao Hinggan Mountains.

研究表明，分布于小兴安岭北部金林林场的兴东群四子山组"混合岩"为一套片麻状石英二长岩-花岗岩侵入体，岩石全岩-矿物Rb-Sr等时线年龄为(482±19) Ma，这表明小兴安岭巨型花岗岩带中存在早古生代岩浆事件。

The original defined adakitesare sodium igneous rocks, they are tonalite, trondhjemite or (plagioclase-rich) granodiorite in whole-rock chemistry; however, the K-rich "C-type" adakite defined by Chinese scholars are potassic igneous rocks, they are granite, quartz monzonite and (alkali feldspar-rich) granodiorite, etc.

最初定义的埃达克岩是钠质火成岩，其全岩化学成分相当于英云闪长岩、奥长花岗岩和花岗闪长岩；而富钾的"C型埃达克岩"全岩化学成分相当于花岗岩、石英二长岩和花岗闪长岩。

The Huashan—Guposhan granitoid belt consists of Tong'an, Huashan, Niumiao, Jinziling, Wuyangshan, Lisong and Guposhan granitoid bodies. Petrographycally, they are diorite, quartz monzonite, monzonitic granite and syenogranite. Dark mafic enclaves are very common. Their major emplacement ages are 160～163 Ma.

花山-姑婆山花岗质杂岩带由同安、花山、牛庙、金子岭、乌羊山、里松和姑婆山等岩体所组成，岩性为闪长岩、石英二长岩、二长花岗岩和正长花岗岩等，富含中基性暗色包体，主要侵位时代为160～163 Ma。
