The stratigraphic sequence exposed in Wandhaya area comprises of marine clastic sediments of Mesozoic, which includes M-III and M-IV of Jumara Formation, Lower Member of Jhuran Formation and Upper Member of Bhuj Formation. Lithofacies erected from the study area are Shale Facies (SF), Oolitic Limestone Facies (OLF), Intercalated Shale Siltstone Facies (ISSF) and Massive Sandstone Facies (MSF). SF is developed in M-III and M-IV of Jumara Formation suggesting its deposition in transition zone. Oolitic Limestone Facies (OLF) occurs only in M-IV of Jumara Formation indicates its depositional environment as offshore region. Intercalated Shale Siltstone Facies (ISSF) is deposited in lower shoreface to transitional and Massive Sandstone Facies (MSF) in foreshore environment, are exposed in Lower Member of Jhuran Formation and also in Upper Member of Bhuj Formation. The sediment characteristics and association of trace fossils in the rocks indicate distinction in sedimentation from foreshore to offshore environments.

古吉拉特邦 Kachchh 大陆 Bhuj 西南 Wandhaya 地区中生代岩石岩相研究

Wandhaya地区出露的地层层序为中生界海相碎屑沉积，包括Jumara组M-III和M-IV、Jhuran组下段和Bhuj组上段。从研究区竖立的岩相有页岩相（SF）、鲕粒灰岩相（OLF）、夹层页岩粉砂岩相（ISSF）和块状砂岩相（MSF）。SF 发育于 Jumara 组的 M-III 和 M-IV，表明其沉积在过渡带。鲕粒灰岩相 (OLF) 仅出现在 Jumara 组的 M-IV 中，表明其沉积环境为近海区域。夹层页岩粉砂岩相 (ISSF) 沉积在前滨环境中的下滨至过渡和块状砂岩相 (MSF)，出露于 Jhuran 组下段和 Bhuj 组上段。岩石中痕量化石的沉积特征和关联表明从前滨到近海环境的沉积不同。
