The investigation indicates that the Shalagang antimony has osculatingrelationship with the Structure but has no selectivity with the host rock: The ore bodyis controlled by the fault zone, which insert into it as a nervation;The host rockincludes chert, carbonaceous slaty rock, altered diorite , altered diabase and so on. Theore-forming epoch of Shalagang antimony is obviously later than era of the host rock,so it is concluded that the Shalagang antimony maybe formed in the late Himalayan.

研究表明，沙拉岗锑矿床与构造关系密切，而对容矿岩石类型无选择性：矿体主要受控于断裂及层间破碎带；主要容矿岩石有硅质岩、碳质板岩、强蚀变中基性火山岩和蚀变辉绿岩等，并以硅质岩为主；矿床成矿时代明显滞后于容矿岩石时代，据此推断沙拉岗锑矿床可能形成于喜山晚期。

目前我国东部的石油勘探工作已进入精细勘探阶段，如何确定陆相地层中薄储层的空间展布规律及其性质已成为一个亟待解决的问题，由于我国东部的绝大多数中、新生代陆相含油盆地大都以薄层砂、泥岩沉积为主，夹有少量薄层碳酸盐岩、页岩及膏盐层，地层岩性和厚度横向变化均较大，而且这些地层的厚度远远低于常规地震勘探的垂向分辨率，因此，从理论上研究沙泥岩薄互层地震反射特征、薄互层组内的单层厚度、子结构厚度、互层组内层数、入射子波类型、主频、采样率等各种因素对反射波特征的影响，将对我们定性或定量求取薄互层组中各单层厚度或薄层组的厚度、预测薄储层的空间展布规律有一定的理论和现实意义。

Sedimentary facies model for mixed sediments of recent reefoid carbonates and siliciclastics is developed from the facies model of fringing and barrier reefs. Based on the sedimentary facies and textures, mixed sediments may be subdivided into 5 types as follows: 1 reef base mixed sedimentary rocks and reef framework mixed sedimentary rocks; 2 reef flat sand-gravel mixed sedimentary rocks; 3 backreef beach-dune gravel-sand mixed sediments; 4 backreef lagoonal sand mixed sediments ; and 5 reef front littoral sand mixed sediments.

礁源与陆源混合沉积相模式是从岸礁一堡礁相模式基础上发展而来，根据其沉积相和沉积结构特徵可以分为5种混合沉积：①礁基混积岩和礁格架混积岩；②礁坪砂砾屑混积岩；③礁后海滩－沙提砾砂屑混合沉积；④礁后泻湖砂屑混合沉积；⑤礁前浅海砂屑混合沉积。

The Mg-rich volcanic rock is also found in the Baitashan Formation of Middle Devonian series of the Saerbulake area, whixh is a typical boninite formed in the forearc setting.

沙尔布拉克中泥盆统北塔山组中也含有富镁火岩-辉石安山岩，它是典型的玻镁安山岩，其形成环境为前弧。

Mature, synrift lacustrine shales of Eocene to Oligocene age and mature, late rift coals and coaly shales of Oligocene to Miocene age are source rocks for oil and gas in two important petroleum systems of the onshore and offshore areas of the Northwest Java Basin. Biogenic gas and carbonate sourced gas have also been identified. These hydrocarbons are trapped primarily in anticlines and fault blocks involving sandstone and carbonate reservoirs.

爪哇盆地西北的沿海地区的两个重要的石油体系中，始新世至渐新世的湖泊页岩、渐新世至中新世晚期裂隙煤和含煤页岩是石油和天然气的矿源岩，鉴别出了生物源气体和碳酸盐源气体，这些烃类被圈闭在背斜和断层中，包括沙岩、碳酸盐岩油储。

The forming of lithologic reservoirs in the Palaeogene of Boxing Sag is generally characterized by multiple hydrocarbon expulsion,expulsion and accumulation coupling,and fourfold genesis controlling reservoir-forming.

博兴洼陷下第三系岩性油藏的形成具有&复式排烃、排聚耦合和四元控藏&的总体特征，而其独特的烃源岩结构和地层压力系统决定了沙四上亚段和沙三段烃源岩在排烃方式、排烃机制以及岩性油藏成藏特点上的不同。
