From studies on geological distinctions, metallization and genetic type of the auto-clastic subgranitic porphyry in Xiling tin deqiu. Sn content of the rock, which is a fa-ctcrized by hidden explosion, and the magma resulted from partial melting of upper mantle and lower crust as proposed by Xu Keqin. Sn content of the rock, which is a fa-vorable Sn-bearing rock as indicated by petrochemical parameters, is 10-22 times as high as that of ordinary granites. Close relationship between diagenesis and minero-genesis is verified by Pb isotope ratio. The tin deposit is classified as porphyry depo-sit in view of the common origin of the deposits and the antoclastic subgranitic porphy-ry. Favorable structure for metallization is the contact-zone as well .as explosive breccia.

作者研究了西岭锡矿床自碎次花岗斑岩岩体的地质特征、含矿性、成因类型。认为自碎次花岗斑岩具有隐爆特征。岩浆来自上地幔至下部地壳物质的部分熔化,属于徐克勤教授所划分的过渡型地壳同熔型花岗岩类。岩体中锡含量是一般花岗岩类的10—22倍,并具有含锡岩体的有利岩石化学条件,铅同位素比值证实了成矿与成岩的紧密联系。锡矿床与自碎次花岗斑岩是同源的,应为斑岩型锡矿床。接触带和爆破角砾岩带是成矿的有利构造部位。

According to geological results gained in recent years, the author holds that"1220 Caldera" with positive landform features does not exist in nature. For example,the development of three complete facies zones within "the caldera", regular varia-tions of the mineral composition and crushed phenocrysts, northward compressionand westward tension shown by secondary fracture structures and concentration of aseries of mineral deposits in the northern and western parts of "the caldera", ----allthese cannot be explained...

According to geological results gained in recent years, the author holds that"1220 Caldera" with positive landform features does not exist in nature. For example,the development of three complete facies zones within "the caldera", regular varia-tions of the mineral composition and crushed phenocrysts, northward compressionand westward tension shown by secondary fracture structures and concentration of aseries of mineral deposits in the northern and western parts of "the caldera", ----allthese cannot be explained by the hypothesis of "1220 Caldera", It may be seen fromabove that the hypothesis of "1220 Caldera"is a false phenomenon, which resultsfrom not strict distinction of two geological masses (subvolcanic rocks and effusivelavas) of similar appearance and different origins in the field work. So what con-trols the 1220 uranium orefield is not a caldera but a subvolcanic crushed graniteporphyry dome characterized by cryptoexplosive phase.

近几年来,我国一些地质工作者把1220岩体误认为地貌上具正地形的破火山口,并把这种具正地形的“破火山口”做为寻找铀矿的一种标志。笔者从近年来所获的资料出发,论证了1220岩体是一个具隐爆相特征的次碎花岗斑岩穹窿体。并对“1220破火山口”及其控铀问题提出异议。

The Qibaoshan Au-Cu deposit is hosted in the Mesozoic central vent type volcanic edifice within the depressed basin of Yishu Rift system. This volcanic edifice, rich in light REE and some other trace elements, is inferred as an anatectic product of the high gold Jiaodong Group. The intermidiate-basicity and intermediate-acidity magma erupted successively formed the ring complex and radial dykes or apophyses due to magma differentiation at depth. Analyses of the trace amount gold in different . magmatites indicate...

The Qibaoshan Au-Cu deposit is hosted in the Mesozoic central vent type volcanic edifice within the depressed basin of Yishu Rift system. This volcanic edifice, rich in light REE and some other trace elements, is inferred as an anatectic product of the high gold Jiaodong Group. The intermidiate-basicity and intermediate-acidity magma erupted successively formed the ring complex and radial dykes or apophyses due to magma differentiation at depth. Analyses of the trace amount gold in different . magmatites indicate that late magmatic quartz diorite prophyrite and granodiorite prophyry have the highest gold contents and closely associated with gold mineralization. After the concealled explosion-breccia pipe was formed,metalliaztions were deposited in the fissures of the pipe. Mineralizad rocks have a planar alteration,predominant in silicification, sericitization and pyritization. In the upper part of the existing orebody within a range of 150 m gold is the main mineralization while in the lower part gold is gradually substituted by copper. Zonality of ore structure has been observed with stockwork and veinlet disseminated ore in the upper part and veinlet disseminated ore in the lower part of the orebody. Ges inclusion studies prove that the disintegration of the orebody has reached into its central part. The main metallic mineral is specularite containing native gold and electrum. Surbordinate minerals are pyrite, chalcopyrite siderite and a very small amount of sulfosalt. It is believed that this Au-Cu deposit can be grouped as porphyry type.

沂沭裂谷系断陷盆地中的中生代中心式火山机构控制着七宝山金铜矿床。从该火山机构富轻稀土和所含微量元素推断,系含金背景值高的胶东群重熔的产物。由于岩浆在深部的分异,先后喷溢出从中基性向中偏酸性转化的环状杂岩体和放射状岩墙、岩枝。分析各岩浆岩的微量金,以晚期石英闪长玢岩和花岗闪长斑岩中含量最高,与金矿化关系最密切。在隐爆角砾岩简形成之后,金属矿化形成于其裂隙中。矿化岩石具面型蚀变,以硅化、绢云母化、黄铁矿化为主。现存矿体上部150米内以金为主,向下以铜为主。矿石构造有分带现象,上部为角砾间的网脉加细脉浸染体。下部只有细脉浸染体。气包裹体研究证明已被剥蚀到矿体中部。金属矿物较简单,主要为镜铁矿含自然金和银金矿,次为黄铁矿、黄铜矿、菱铁矿和微量硫盐。认为该矿为斑岩型金铜矿床。
