As a result of a deep burial depth (> 6.5 km), the depositional history of the Early to Middle Ordovician carbonate platform in the Shuntuoguole Low Uplift (Tarim Basin, NW China) has been difficult to unravel, leading to problems in understanding the controls of the facies distribution, particularly in terms of petroleum exploration. Integrated with geophysical surveys, detailed sedimentological observations document the platform evolution and show that a carbonate ramp system developed in the Shuntuoguole Low Uplift during the Early-Middle Ordovician, with twelve lithofacies types arranged into two facies associations, including peritidal to semi-restricted subtidal and open-marine subtidal facies. Based on the tempo-spatial distribution of lithofacies, seven third-order depositional sequences are identified, each composed of a transgressive lower package and a regressive upper part. Their sequence boundaries are commonly characterised by a transitional zone with no obvious subaerial exposure features. The correlation of relative sea-level (or accommodation space) changes derived from the vertical stacking pattern of facies with the global sea-level curve of Haq and Schutter (2008) and sea-level oscillations of coeval successions worldwide suggests that eustatic sea-level fluctuations were the overriding factor controlling the development and evolution of this carbonate ramp during the Early-Middle Ordovician. Meanwhile, regional or local tectonic subsidence and environmental factors (e.g. palaeoclimate and prevailing wind) also exerted an influence on the depositional processes of the Shuntuoguole Low Uplift over this time interval.
由于埋藏深度较深（6.5 千米），顺图郭勒低隆起（中国西北部塔里木盆地）早中奥陶世碳酸盐岩平台的沉积历史一直难以揭示，导致在了解岩相分布的控制因素方面存在问题，特别是在石油勘探方面。结合地球物理勘探，详细的沉积学观察记录了平台的演化过程，并表明在早-中奥陶世期间，顺图郭勒低隆起发育了碳酸盐岩斜坡系统，有十二种岩性类型，分为两个面系，包括潮下带至半限制潮下带和开放海相潮下带。根据岩性的时间-空间分布，确定了七个三阶沉积序列，每个序列都由下部的横向组合和上部的回归组合组成。它们的序列边界通常是一个过渡带，没有明显的次海相暴露特征。根据面层垂直堆积模式得出的相对海平面（或容纳空间）变化与 Haq 和 Schutter（2008 年）的全球海平面曲线以及全球共生演替的海平面振荡的相关性表明，在早奥陶世-中奥陶世期间，侵蚀性海平面波动是控制该碳酸盐斜坡发育和演化的首要因素。同时，区域或地方构造沉降和环境因素（如古气候和盛行风）也对这一时期的顺图郭勒低隆起沉积过程产生了影响。

Biophotonic nanostructures rarely withstand fossilization processes occurring after burial over geologic time. Even more distinctive is a change introduced to the optical properties during diagenetic processes resulting in a different optical appearance. Here, we report and explain the optical appearance of centric diatom frustules obtained from ash-bearing carbonate-cemented concretions on the Greifswalder Oie island (Pomeranian Bay, Germany, southern Baltic Sea). The ultrastructural and mineralogical analysis of the fossil frustules were carried out using electron microscopy techniques and were correlated to the macroscopic and microscopic optical appearance of the frustules before and after acid etching. The unique optical properties of the fossil diatoms were associated with diagenetic nanocrystalline calcite filling the frustules’ areolae. This fill created the macroscopic pale-yellow colour of many frustules, a microscopic iridescence probably associated with diffraction grating behaviour, and microscopic colour rings. The results highlight the unique permineralization process of diatom frustules and might be an addition to the emerging studies on frustule optics and photonics.
