查询词典 quartz diorite

The formation process of the rocks is divided for thefirst time into three cycles corresponding to J2, J3, and K1, respectively, and each cycle into early,middle, and late periods based on intruding contact relationship among different types ofgranitoids.3. A detailed study on the petrological characteristics of different cycles of theMesozoic granitoids supports classification of the rocks into three lithological associationsincluding A-type, high-K calc-alkaline, and calc-alkaline granitoids, of which the first associationbelongs to alkaline series, and the others belong to calc-alkaline series. It is shown that thelithologies change from diorite, quartz monzonite, and granodiorite to monzonitic graniteand syenogranite with periods from early to late in each cycle.4. A preliminary summarization hasbeen made on the evolution characteristics of the rocks.

首次将中生代花岗岩类划分为J2旋回、J3旋回、K1旋回等三个旋回，并依据不同岩石类型间的侵入接触关系，将每个旋回又划分为早、中、晚三期。3、在详细研究区内中生代不同时期花岗岩类岩石特征的基础上，首次将区内中生代花岗岩类划分为碱性系列碱质A型花岗岩类以及钙碱性系列高钾钙碱性花岗岩类和钙碱性花岗岩类等二个系列三种岩石组合类型，确定每个旋回从早期到晚期，岩石均具有从闪长岩、花岗闪长岩、石英二长岩-二长花岗岩-正长花岗岩演化的趋势。4、初步总结了区内中生代花岗岩类的演化特征。

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。

According to logging results of 167 boreholes and chemical analyses of 24 369 samples as well as characteristics of element distribution at 4 000 m, 3 950 m and 3 900 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 hornblendequartz 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4000 m、3950 m、3900 m水平面的Cu、Au、Ag、Mo、Mn、P b、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。

This study was only focused on the No.Ⅰore body. Based on detailed logging and dating results, it is considered that mineralization of the Cu_Au porphyry occurred in Late Jurassic. The formation of the ore body is related to the Late Jurassic augen quartz phenocryst_bearing hornblende_quartz diorite porphyrite intrusion（J3δομ）.

通过对雄村铜金矿床Ⅰ号矿体详细的地质编录和测年成果，发现雄村斑岩型铜矿床形成于晚侏罗世，矿体的形成与晚侏罗世侵位的、含眼球状石英斑晶的闪长玢岩（J3δομ）有关，成矿岩体呈不规则的岩枝状，全岩矿化，岩体中Au的平均品位大于1g/t，Cu含量大于0.7 %。

So the meta-granitoids can he recognized and separated from the metamorphic sequences. They are grouped as the Meoproterozoic-Neoproterozoic gneissoid granite-monzogranite-granodiorite, with their isotope ages of 953.4 Ma to 1450 Ma, and the Sinian schistostose quartz monzogranite diorite.
