始新世早期放射虫动物群发现于萨嘎地区泥砂质混杂堆积中,包括:Amphisphaera coronata (Ehrenberg);Buryella hannae Bak & Barwicz-Piskorz;Buryella clinata Foreman;Buryella tetradica Foreman;Calocycloma ampulla (Ehrenberg);Lamptonium fabaeforme constrictum Riedel and Sanfilippo;Lamptonium pennatum Foreman;Lithomespilus coronatus Squinabol;Lamptonium(?)colymbus Foreman等分子,属始新世早期典型生物组合,放射虫动物群时代和沉积环境表明,研究区在始新世早期特提斯洋并未完全关闭,印度与欧亚板块之间仍存在深水盆地,板块的全面拼合造山作用至少发生在始新世早期之后.
Early Eocene radiolarians fauna found in the Saga area of muddy mixed accumulation, including: Amphisphaera coronata (Ehrenberg); Buryella hannae Bak & Barwicz-Piskorz; Buryella clinata Foreman; Buryella tetradica Foreman; Calocycloma ampulla (Ehrenberg); Lamptonium Fabaeforme constrictum Riedel and Sanfilippo; Lamptonium pennatum Foreman; Lithomespilus coronatus Squinabol; Lamptonium (?) colymbus Foreman and other molecules, belonging to the typical Eocene biological assemblage. The age and sedimentary environment of the radiolarian fauna indicate that the study area was located in the early Eocene The Tess ocean did not close completely. There is still a deep-water basin between India and the Eurasian plate. The comprehensive orogeny of the plate occurred at least after the early Eocene.
