%X Late Carboniferous carbonate buildups are well exposed in Northern Xinjiang, China, where they usually form some mound like or escarpments along both flanks of the Tianshan Mountains. Three types of the carbonate buildups have been recognized, including mounds, organic banks and biostromes. Mounds, as a main type of the carbonate buildups in eastern Tianshan Mountains, are characterized by cores of massive nonbedded algea and bryozoan packstones and wackestones. These limestones contain high percentages of lime mud and fine bioclastic debris as interstitial material. Besides packstones and wackestones, other types of the rocks, such as wacke packstones, framestones and bafflestones can be found in some buildups in the region. The diagenesis of the carbonate buildups have been discussed in detail, especially the cementation of the mounds. Four types of cements have been identified:a) peloidal micritic calcite cenment; b) fiberous calcite cement. c) rediaxial calcite cement which is composed of radially arranged prismatic calcite crystals with curved cleavages and rombic ends; and d) blocky calcite cement. Based on the general characteristics, the carbonate buildups growth development in eastern Tianshan Mountains are very similar to those in Waulsortian buildups, Europe in organic and carbonate cement components.
