造盆作用及成矿盆地的历史──动力综合分类

关于盆地的分类，不少学者提出过有意义的方案。它们主要是从某个单一角度进行：或者是从历史角度分析，或者是从动力角度分析，为了更较全面地认识它们，以求得更有效地指导找矿勘探，作者把两种分析方法结合起来，提出一个综合分类方案。按历史－动力综合分类，造盆作用及盆地可划分为三大类：大洋壳型、雏陆壳（过渡壳）型及大陆壳型。大洋壳型中可细分为活动区型（主要为拉张式）和稳定区型。雏陆壳型包括前地槽型（其中可分出多种活动区型及稳定区型，有待详究；活动区型中拉张式多见）及地槽前期型（主为拉张式）．大陆壳型中计有地槽后期（褶皱带）型（挤压式或拉张式）、地台型（主为陷落式，偶为张陷式－－断拉谷Ｑｕｌａｃｏｇｅｎ）和地洼型（挤压式、拉张式或压张式）。

Bacterial contribution to sedimentary organic matter; a comparative study of lipid moieties in bacteria and Recent sediments

A systematic study of the lipid composition of thirteen bacterial species and three Recent sediments (methanogenic sediment, cyanobacterial mat and evaporative gypsum crust) was undertaken in an attempt to recognize bacterial organic matter in sediments. A sequential method, which distinguishes between three different modes of occurrence of lipid moieties (free, OH⁻- and H⁺-labile), was applied. The acid-labile fractions are discussed.The three main groups of bacteria, archaebacteria, gram-positive eubacteria and gram-negative eubacteria, are easily distinguished. Methanogenic and extremely halophilic archaebacteria are characterized by the presence of diphytanyl glyceryl ether and the absence of fatty acids. The gram-positive eubacteria contain primarily iso- and anteiso-branched fatty acids whereas the gram-negative bacteria and sediments are dominated by β- and α-hydroxy fatty acids. A wide variety of H⁺-labile hydroxy fatty acids was observed which included several, as yet unknown, structures.β-Hydroxy fatty acids in this H⁺-labile mode of occurrence are exclusively present in bacteria. Their distribution patterns in sediments are considered “fingerprints” of past and present bacterial populations. The specific differences in β -hydroxy fatty acid compositions observed in the different bacteria and the three sediments investigated, suggest that amide-linked β-hydroxy fatty acid patterns are useful as markers of bacterial populations and therefore of environmental conditions.

扬子板块的地壳演化与地层对比

扬子板块是在古元古－新太古宙的古陆核基础上发展演化而成。吕梁运动以前，以川中微型陆块为主体的若干个小型古陆块组成向北西突出的牛轭形陆块带。中元古宙在牛轭形陆块带的东西两侧形成海沟岛弧系，沉积一套弧前及弧后的优地槽和旰地槽建造。１０－１１亿年时的东川运动使沟弧系褶皱回返，固结为陆新元古宙早期产生大陆裂谷，形成五一套裂谷建造，晋宁运动使扬子板块整体固结新元古宙晚发育山前磨拉建造、冰碛层及碳酸盐盖层。全     

中国东北及邻区大陆边缘构造

中国东北及邻区大陆边缘包括两个构造带。内带由裂解的古陆碎块组成，其北部与古亚洲洋的演化有关，南部与古太平洋演化有关。外带由中生代地体组成。它们是晚古生代到早中生代的洋壳碎块与晚中生代的深海沟堆积组成的混杂体带。古亚洲洋封闭后到现代太平洋板块活动前，即由泥盆纪到侏罗纪曾存在过另一个大洋－古太平洋，其洋底扩张活动形成了上述的构造带。晚侏罗世后本区发育左旋平移断裂系，晚白垩世一早第三纪形成了大陆缘火山－

由深源远震体波记录反演华北北部地壳上地幔速度结构

重点研究的地区为河北省北部包括京津地区，以及山西、内蒙的部分地区，在此区选取了２９个台站；在向东延伸的背景区，选取了６个台站。利用这些台站的深源远震体波记录资料，通过选取介质结构模型，计算理论地震图，与观测图进行拟合，以确定地震台下介质结构的可接受模型。在拟合时，对每个地震台站都选择若干次深源远震的体波记录作为观测图。对每个地震台站一般都算出６０个不同模型的理论图。实际上做出的结果比地壳深，为大约８０ｋｍ（即大致相当于岩石层或称岩石圈）厚度内的地壳上地幔介质结构，它们大都由１０层左右的介质组成。通过波形拟合共给出了上述３５个台站下的壳幔介质分层结构。并由此给出了Ｍｏｈｏ面的轮廓。     

A crustal seismic velocity model for the UK, Ireland and surrounding seas

A regional model of the 3-D variation in seismic P -wave velocity structure in the crust of NW Europe has been compiled from wide-angle reflection/refraction profiles. Along each 2-D profile a velocity–depth function has been digitised at 5 km intervals. These 1-D velocity functions were mapped into three dimensions using ordinary kriging with weights determined to minimise the difference between digitised and interpolated values. An analysis of variograms of the digitised data suggested a radial isotropic weighting scheme was most appropriate. Horizontal dimensions of the model cells are optimised at 40 × 40 km and the vertical dimension at 1 km. The resulting model provides a higher resolution image of the 3-D variation in seismic velocity structure of the UK, Ireland and surrounding areas than existing models. The construction of the model through kriging allows the uncertainty in the velocity structure to be assessed. This uncertainty indicates the high density of data required to confidently interpolate the crustal velocity structure, and shows that for this region the velocity is poorly constrained for large areas away from the input data.
