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）.

The orebodies of the Gongpoquan copper orefield occur in the quartz dioritic porphyry body, granodioritic porphyrite body and dacitc porphyry body.

公婆泉铜矿矿体的赋矿围岩主要为石英闪长玢岩、花岗闪长斑岩和英安斑岩，这些含铜斑岩体形成于晚志留-早泥盆世板块俯冲碰撞过程中，受断裂和火山机构控制。

This paper reports the investigation on the petrology of spinel harzburgite and olivine pyroxenite in the Darbut ophiolitic mélange, as well as the worm-like intergrowth texture composed of Cr-spinel and orthopyroxene wide-spreading in harzburgite. Our study shows that the observed intergrowth texture is not a graphic texture or a symplectite as assumed by previous research, instead, it is a product of the evolution of the Cr-rich magma formed after the melting of the primitive mantle.

通过研究西准噶尔达拉布特蛇绿混杂岩中方辉橄榄岩和橄榄辉石岩的岩石学特征，分析方辉橄榄岩广泛发育的铬尖晶石和斜方辉石构成的蠕虫状共生连晶结构的成因，得出结论认为：这种共生连晶结构不是前人所认为的文象结构或者石榴石的后成合晶，而是原始地幔岩熔融形成富铬岩浆的演化产物。

Mineral magnetic parameters, including magnetic susceptibility, frequency dependent susceptibility, isothermal remanent magnetization, anhysteretic remanent magnetization, temperature-dependence of susceptibility, were measured on quartzite and surface soil derived from quartzite. The results in combination with the microscope observation indicated little magnetic mineral in quartzite but a few magnetite, maghemite, iron oxyhydroxides in surface soil. The magnetic grains were mainly superparamagnetic and stable single domain. Maghemite is secondary mineral formed in the process of pedogenesis.

通过对石英岩及发育于石英岩之上表土的磁化率、频率磁化率χ(下标 fd、等温剩磁、非磁滞剩磁ARM0、k-T曲线等磁学参数测定和石英岩显微镜下观察，结果表明，石英岩中磁性矿物含量极少；表土中含磁铁矿、磁赤铁矿、铁的氢氧化物等磁性矿物，磁性矿物主要以稳定单畴(SSD和超顺磁性颗粒形式存在，磁赤铁矿是石英岩在成土过程中形成的次生矿物。

The Fenghuangshan pluton, which consists of granodiorite and quartz monzodiorite, is the main part of the Fenghuangshan ore field Zircon SHRIMP 206Pb/238U dating shows that the Fenghuangshan pluton formed at (144.2±2.3) Ma, belonging to the Late Jurassic era, which is in accordance with most of metallogenic plutons of the Tongling metallogenic cluster area.

凤凰山岩体为凤凰山矿田的主要组成部分，主要岩石类型为花岗闪长岩、石英二长闪长岩。根据精确锆石SHRIMP测年结果，凤凰山岩体206Pb/238U年龄为(144.2±2.3)Ma，是晚侏罗世形成的一个典型岩体，和铜陵矿集区主要成矿岩体的形成时代一致。

The second group are the mixtures of Jurassic coal-formed oils and Cretaceous-derived oils. The carbon isotope, n-alkanes and isoprenoids compositions of these oils are similar to core extracts from Jurassic coal measures. However, sterane and terpane compositions of these oils show affinity to Cretaceous source rocks. It is deduced that coal-formed oils dissolved the biomarker-rich Cretaceous bitumen of relatively low thermal maturity, and overprinting occurs during oil migration.

第二类原油具有侏罗系煤系烃源岩与白垩系湖相泥质烃源岩混源的特点，这类原油的碳同位素组成、正构烷烃分布特征和姥植比等均表现出煤成油的特征，但甾、萜烷烃类化合物组成与白垩系烃源岩接近，推测是由于侏罗系煤成油在向上运移成藏过程中，受到成熟度相对较低、生物标志物相对丰富的白垩系烃源岩的浸析作用所致。

Furthermore, large-scale fold and fault structure hasn't been found around the Tianchi Lake, but the original prismatic joints and radial joints developed well in the trachyte, so the rock mass is dissected into fractured fragmental structure and the integration of rock mass is further destroyed.

在构造方面，长白山天池周围虽然没有发现大规模的褶皱断裂构造，但粗面岩中原生柱状节理、放射状节理十分发育，这些节理裂隙将岩体切割成十分破碎的碎裂结构，使岩体极易产生岩崩、落石，使岩体的完整性遭到了进一步的破坏。

Based on the detailed study of seismic tomography image in South China, and according to the geotectonic environment and shape and heat of asthenosphere upwelling, we divided the structure of lithosphereasthenosphere at the Mesozoic upper mantle of Eastern China into three types.(1)Continental platform area (North China platform and Yangtze platform): asthenosphere upwelled along paleorift; over the plume head, the granitic rocks of crust and mantle mixed and correspondingly, Au, Cu, Mo, PbZn, etc. mineralizationconcentrated regions were formed; and at the steep contact belt of asthenosphere and the thick area of lithosphere, mediatebasic complex was formed.(2)Central area of fold zone: asthenosphere was "recumbent" at suitable depth, with adequate heat and in a great extent; by heat conduction, the interior of partial crust remelted, and the crustsource granitic rocks, and correspondingly, W, Sn and rare elements mineralizationconcentrated regions were formed.

在深入研究华南地震层析成像的基础上，按照大地构造环境和软流圈上涌形状和热度，将中国东部中生代上地幔中岩石圈软流圈构造划分为3类：(1)陆台区，软流圈沿古裂陷上涌，其柱头上方形成幔壳混熔花岗质岩及相应Au、Cu、Mo、PbZn等矿集区，并于软流圈与岩石圈厚区之陡接触带形成中基性杂岩及相应Fe矿集区；(2)褶皱带中心区，软流圈在适当深度、热量充足、较大范围内&平卧&，因热传导而致使地壳内物质部分重熔，形成壳源型花岗质岩及相应的W、Sn、稀有元素矿集区；(3)褶皱带边缘区(大兴安岭南部及华南南缘)，在软流圈上涌柱上方形成幔源或幔壳混熔的花岗质岩，相应为Cu、Au、PbZn、Mo、Ag矿集区。

Igneous intrusions such as batholiths, laccoliths, dikes, and sills, push upwards into the overlying rock, and crystallize as they intrude.
