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.

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。

The Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on. It had a beneficial geological condition to develope sublacustrine slump turbidite fans in Jishan, Jiangjiadian and Wawu.

利用地震、钻井、测井等资料，将古近系沙河街组划分出7个三级层序，通过剖面沉积学分析，以优势相原则绘制不同时期各亚段沉积体系平面分布图：沙四下总体以洪水-漫湖沉积为特征，沙四上沉积时期是在滨浅湖背景之上发育了曲流河三角洲和辫状河三角洲沉积；沙三段沉积时期南部主要发育辫状河、曲流河三角洲，西北部地区发育曲流河三角洲，中部地区主要为深湖—半深湖沉积；由沙三下至沙三上，西北部三角洲规模逐渐增大，沉积范围逐渐向东、东南方向推进；沙二段沉积时期为滨浅湖沉积，在背景之上广泛发育了辫状河三角洲和三角洲沉积；沙一段以滨浅湖滩坝沉积为特征，南部发育了曲流河三角洲和辫状河三角洲沉积；沉积地层中的岩性圈闭以滑塌浊积岩岩性圈闭和地层侧向尖灭型岩性圈闭为主，其形成和分布主要受盆地结构、沉积古地貌和构造活动强度等因素控制，北部基山、南部江家店和瓦屋具有发育滑塌浊积扇的良好地质条件。

In view of a little thickness and limited oil-forming potential of source rock of Member 2 of the Shahejie Formation, the source rock in Member 3 of the Shahejie Formation is considered as the main source of oil and gas.
