放射虫

Analysis of the morphological feature, diversity and abundance of graptolite, brachiopod and radiolariaindicated that the sea-level in the Yangtze basin underwent the change from rising to falling, then to risingagain during the latest Ordovician to the earliest Silurian interval, and the maxium rising episode appeared inthe lower Tangyagraptus typicus Subzone and the maxium falling at the top of the Guanyinqiao bed.

笔石、腕足类、放射虫的形态、分异度和丰度的研究表明：扬子海盆晚奥陶世晚期至志留纪初期，总体上，海平面经历了上升→下降→上升的变化，海平面上升的最大阶段发生在Tangyagraptus typicus亚带下部，到观音桥层顶部，海平面下降到最低点。

Radiolaria is an important fauna among the marine micropaleontology, whose ecology knowledge is the base of paleoceanographical and paleoenvironmental reconstruction.

中国加入综合大洋钻探计划，势必会加快[JP2]我国古海洋学的研究步伐，放射虫作为海洋微体古生物中的一个重要类群，其生态学知识是重建古海洋、古环境的基础。

Distribution of biogenic silica content in surface sediments from deep water areas showed that it could not only reflect the paleoproductivity of siliceous micropaleontology in surface waters, but also indicate the strong or feeble upwelling. Thus, it was further confirmed that using biogenic silica content in sediments to trace upwelling and its change was effective and reliable. The analyzed result showed that radiolaria and poriferous specula have more contribution for biogenic opal, comparing with diatom in surface sediments from the northern studied area, probably owing to the diatom dissolved easily away and eaten by other organisms with little effort.

深水区表层沉积物中生物硅的含量分布表明，其不仅能反映出表层水体中硅质生物的古生产力水平，而且还能指示上升流的强弱，从而进一步证实了利用沉积物中生物硅含量来追踪上升流发育和变化的有效性与可信度研究结果还显示，在研究区域中北部表层沉积生物硅中放射虫和海绵骨针较硅藻占有更大的比重，这可能是由于硅藻易被溶解并易被其他生物体摄食的缘故。

The results obtained in this study are as follows:(1) The result of species analysis shows that Spumellaria was dominant in the more than 190 species identified, and the radiolarian assemblage of the northern area of Okinawa Trough belong to warm-water fauna compared to their available ecology knowledge.

结果表明：（1）初步鉴定190个种，其中泡沫虫目Spumellaria在种和个体数量上占绝对优势，与有关资料对照表明，冲绳海槽北部的放射虫组合属热带大洋暖水动物群。

Amaranth radiolarian silicate close connected with ophiolite slices are discovered in "Ma'erzheng Fm." along Huashxia — Long Stone Hill for the first time, and abyssal Early Permian radiolarians are got, thus provide important reference date for the forming age of ophiolite in this belt.

2首次在花石峡—长石头山一带的"马尔争组"中发现与该带蛇绿岩岩片有密切联系的紫红色放射虫硅质岩，并分离出丰富的深海相早二叠世放射虫化石，为该带蛇绿岩的形成时代提供了有重要价值的参考年龄。

It was revealed that the radiolarians in the pebbles dated from Tournaisian to early Visean in age.Geochemical characteristics of the pebbles implied that the radiolarian was deposited in a small oceanic basin,indicating that Kelamaili oceanic basin was closed in the late Early Carboniferous and a quick uprising occurred in the Kelamaili orogenic belt during early Jurassic.

关于两板块缝合的时代，地质学者存在较大争论，有早古生代、泥盆纪、早石炭世不同观点：蔡文俊(1986)根据放射虫研究认为缝合时代为早石炭世[1]，何国琦等(2001)认为克拉麦里造山带是由克拉麦里早古生代洋闭合形成[2]，舒良树和王玉净(2003)根据放射虫动物群对比认为克拉麦里蛇绿岩形成年龄为晚泥盆世法门期—早石炭世杜内

China has participated in such deepsea research programs as IODP, which should accelerate the step of the study of paleoceanography.

随着放射虫在古海洋环境研究中的广泛应用以及研究手段的改进，放射虫现代生态学研究在世界各大洋得到了广泛开展。
