Abstract：The Ordovician reef reservoirs in the Tarim Basin have been receiving more and more attention. The present research describes the reefs in Lianglitage area, Tarim Basin: NYG-1 reef (at the top of Yingshan Formation) and NYG-2 reef (at the bottom of Yijianfang Formation). Biotypes, lithologies, and sedimentary facies units of these two reefs were detailed documented, using detailed field observations, measurements, and thin section identifications. The results suggest that reef-building organisms are mainly composed of calathiums and that lithology associated with reefs is bafflestones, boundstones, bioclastic wackestones, bioclastic packstones, intraclastic packstones, bioclastic grainstones, intraclastic grainstones, and peloidal grainstones. Facies units in the NYG-1 reef mainly contain reef base, reef core, reef top, reef flank and reef cap. However, the NYG-2 reef consist only of reef base, reef core and reef cap. The Yingshan Formation is rich in calathium-baffle reefs, while Yijianfang Formation is dominated by calathium baffle-binding reefs. Reefs in Yingshan Formation are in the shape of circle-like and intra-platform patches, without obvious directional anisotropies. Reefs in Yijianfang Formation, in contrast, contain platform margin reefs that extensively show the vertical migration characteristics. Both formations have experienced three phases of evolutions, namely colonization, vertical aggradation, and capping. The difference lies mainly in the capping phase. More specifically, during the deposition of Yingshan Formation, the rapid decrease of sea levels and the high water energy led to the perish of calathium and the formation of grainstones, whereas the rise of sea levels and the development of considerable planktonic algae organisms caused the suffocation of calathiums. To conclude, this research provides insights into building reefs depositional models of the Tarim Basin and exploring new methods of comparative study on outcrops and underground reefs.
