西藏南部海相第三系自下而上划分为:基堵拉组、宗浦组和遮普惹组。基堵拉组的归属直接关系到白垩——第三系的界线问题。以往在证据不充分的情况下将基堵拉组归于白垩系。本次工作在该组中找到了具时代意义的化石,有双壳类、介形虫、有孔虫等。通过化石群的研究确定了基堵拉组属于古新世丹宁早期。白垩—第三系界线应位于宗山组与基堵拉组之间。通过基堵拉组的横向对比得出了该组在空间上穿时的结论。浮游有孔虫动物群的发现确定了本区最高海相层为遮普惹组上段,时代属于始新世晚期。 西藏第三纪有孔虫类型丰富。据动物群的古生态研究得出了不同时代的有孔虫生物相:丹宁期为Rotalia生物相和Textularia生物相;朗德期为Miscellanea生物相和Ranikotbalia生物相;伊普尔期至路坦丁期包括Orbitolites生物相、Assilina生物相及冈底斯有孔虫生物相;普里亚波期以Globigerina生物相为特征。据有孔虫生物相的特征及氧碳稳定同位素的测试结果综合得出了西藏南部第三纪包括两次海侵旋回,即古新世和始新世旋回。二者又分别包括两回次一级的旋回,即古新世的丹宁期旋回和朗德期旋回;始新世的伊普尔期至路坦丁期旋回和普里...

The Nanling of South China is one of the most important areas of nonferrous metal mineral resources. Based on incomplete statistical figures, strata-bound lead-zinc, pyrite, tungsten,tin, mercury, antimony and barite ore deposits have been found in Devonian of this area. There are ten's medium to large scale deposits ezplorated and numbers of small deposits spread far and wide. According to genetic types, these deposits can be classified into diagenetic, diagenetic-epigenetic, volcanic exhalation-sedimentary, superimposed and mixed hydrothrmal ore deposits. Four metallogentic models have been established: 1. submarine vadose circulating volcanic exhalation-deposition; 2. basinal diagenetic compactive fluids; 3. basinal thermal brine; 4. mixed hydrothermal metallogenic model. Although these strata-bound deposits are different in types and genesis, many similarities in their ore-controlling factors and distributon may be found. The main controlling factors are stratigraphy (formation), lithofacies and tectonic setting. Thereby, it is considered that any geologic factor controlling the ore formation could not be treated in isolation. The formation of any large scale ore deposit should be considered as the result of the coaction of various geological factors in certain geological settings, and those factors affect and interact commonly each other. The stratigraphic horizon, lithofacies and tectonic setting are thought as main factors for controlling the diagenetic-epigenetic strata-bound ore deposits, and three factors are concordant spatially. When the formation of ttrata-bound ore deposits are related to magmatism, the regional large fault, lithofacies zone, magmatic activity and metallogenesis often show the consistency. That is, the fault controlled early the lithofacies (or volcanic activity), and subsequently controlled the emplacement of magmatic rocks and the migration, circulation and final enrichment of the metallogenetic solutions.

南岭地区是中国有色金属矿产资源重要基地之一。据不完全统计,位于泥盆系地层中的层控铅锌、黄铁矿、钨、锡、汞、重晶石等矿床,已有大、中型矿床达数十个,小型矿床更是星罗棋布。按成因类型分为成岩矿床、成岩-后生矿床、火山喷气-沉积矿床、岩浆热液叠加矿床和混合热液矿床。相应地建立了四种成矿模式,即与火山作用有关的海底渗流循环喷气-沉积成矿,成岩压实水成矿,热卤水成矿,混合热液成矿。虽然泥盆系层控矿床种类多、成因类型复杂,其控矿因素和分布主要受层、相、位控制,本区绝大多数层控矿床赋存于区域不整合面之上,中、上泥盆统海侵旋回的碎屑岩建造向碳酸盐建造的过渡部位;控矿的主要岩相古地理类型是被台盆分割的台地边缘生物礁和泻湖、潮坪,或古陆边缘的生物礁和局限台地;本区绝大多数层控矿床集中分布于北西向丹池断裂带、北北东向冷水江-龙胜断裂带的交汇处,位于前泥盆系构造隆起边缘或泥盆系构造盆地边缘。混合热液矿床还与燕山期的岩浆活动有关。空间分布上成矿带、构造带和岩相带之间有明显的一致性。

A complete Holocene marine transgression cycle has been revealed by quan-titative micropaleontological analyses of ten sediment cores taken from the north-eastern waters of Beibu Gulf (Gulf of Tonkin) off Guangxi Province.The Holocene transgression strata vary in lithology and micro-paleontology in three parts of the studied sea area:l)in the eastern part near 20m isobath the Holocene deposits are composed of greenish-grey silty clay and clay, with microfauna dominated by Schackoinella globosa; 2) in the middle...

A complete Holocene marine transgression cycle has been revealed by quan-titative micropaleontological analyses of ten sediment cores taken from the north-eastern waters of Beibu Gulf (Gulf of Tonkin) off Guangxi Province.The Holocene transgression strata vary in lithology and micro-paleontology in three parts of the studied sea area:l)in the eastern part near 20m isobath the Holocene deposits are composed of greenish-grey silty clay and clay, with microfauna dominated by Schackoinella globosa; 2) in the middle and western parts near 20m isobath the deposits of Holocene transgression consist of muddy sand and the microfauna is characterized by Hanzawaia nip-ponica as its main component; 3) in the area between 5m and 15m isobaths the Holocene transgression strata are composed of muddy sand, silty clay and sand, with Ammonia beccarii var. as the major element in its microfauna.The time and history of Holocene transgression in the area under consideration have been determined based on a comparison of the microfaunas with their modern counterparts and on carbon-14 dates.It is found that the Holocene trahgsgression reached the studied area at the beginning of the Atlantic time about 8,000y BP. Sedimentary records of the early stage of transgression are representd by marine-continental transitional facies. Then the transgression enhanced its influence and reached its maximum about 5,800-4,000y BP.

通过对北部湾东北部10个柱状样进行微体古生物定量分析,揭示了全新世一个完整的海侵旋回。区内发现了Ammonia beccarii var.,Schackoinella globosa,Hanzawaia nip-ponica等三个主要微体古生物群,结合~14c测定年龄资料和岩性,推断了本区全新世海侵的时间和历史,确定本区大约距今8000a左右的大西洋期开始接受海侵,距今4000—5800a前达到最高潮。
