“…The Surat Basin located in the eastern Australia has deposited extensive deltaic deposits comprising of Precipice Sandstone and Evergreen Formation. The facies association of the delta consists of braidplain, delta plain, delta dominated shoreface, tide‐dominated shoreline, and marine shoals (La Croix et al, 2020). The delta distribution during the Early Jurassic has also been recorded globally, i.e.…”

The study aims to establish the palynostratigraphy, tectonostratigraphy, and palaeoclimate of early Jurassic deltaic strata of the Datta Formation deposited on the northwestern margin of the Indian Plate, Eastern Tethys. Two palynomorph Oppel Biozones namely Quadraeculinaanellae formis-Chasmatosporites cf. elegans and Callialasporites turbatus were erected which suggest an Hettangian-Bajocian age for the Datta Formation. The palynofacies integrated with established lithofacies data indicate the dominance of delta plain settings in the western Salt Range and Trans-Indus Ranges. Such clastic dominated facies truncated along palaeohighs and marine settings in its surroundings, offer good chances of stratigraphic traps within the unit.The literature review suggests that the deposition of deltaic sediments occurred in rift settings, which dominated Gondwana during the Early Jurassic. Such synchronous rift settings with associated continental and deltaic sediments are recorded in almost all continents of Gondwana affinity, thus the Datta Formation is part of a regional delta system. The dominance of Araucariaceae in association with Cycadaceae, as well as the evergreen trees of Cyatheaceae and Matoniaceae within the Datta Formation, indicates warm humid conditions during the deposition of the studied unit.

“…complex consisting of a series of sandstones and low-permeability mudstone units of variable porosity, permeability, and mineralogy (Golab et al, 2015;Pearce et al, 2016;La Croix et al, 2019b). The Westgrove Ironstone Member is located within the Evergreen Formation (Figure 1), and is also considered a regional-scale seal (La Croix et al, 2019a;La Croix et al, 2020a;La Croix et al, 2020b;Pearce et al, 2021c). The Hutton Sandstone is the low-salinity aquifer overlying the Evergreen Formation, and in other areas of the Surat Basin, both the Hutton Sandstone and the Precipice Sandstone are sources of water for agriculture, mining, livestock, or town water bores (Suckow et al, 2018;Hayes et al, 2020).…”

Metal Mobilization From CO2 Storage Cap-Rocks: Experimental Reactions With Pure CO2 or CO2 SO2 NO

et al. 2022

CO2 geological storage will be needed as part of the transition to lower greenhouse gas emissions. During CO2 storage, the mobilization of metals from minerals to formation water via CO2 water rock reactions may be a concern for water quality. The sources, behavior, and fate of metals, however, are not well understood. Metals in minerals of calcite cemented sandstone, feldspar-rich sandstone, and ironstone seal drill cores from a target storage site were characterized. The cores were reacted with low-salinity water and pure supercritical CO2 or impure CO2 with SO2 and nitric oxide (NO), under reservoir conditions. Calcite cemented core underwent calcite dissolution with chlorite, plagioclase, and sulfide alteration. The highest concentrations of calcium and manganese were released in the reaction of calcite cemented sandstone seal, with the lowest mobilized arsenic concentration. Pure CO2 reaction of the feldspar-rich sandstone seal resulted in calcite dissolution, with plagioclase, chlorite, kaolinite, illite, and sulfides corroded. Impure CO2 reaction of the feldspar-rich sandstone led to additional corrosion of apatite, pyrite, and sphalerite cements. Generally, dissolved iron, lead, zinc, and arsenic were released and then re-precipitated in oxide minerals or adsorbed. Calcium, manganese, and strontium were released primarily from calcite cement dissolution. Plagioclase corrosion was a second source of dissolved strontium, and chlorite dissolution a second source of manganese. Although sulfides contained higher concentrations of metals, the higher reactivity of carbonates meant that the latter were the main sources contributing to dissolved metal concentrations. The mineral content of the seal cores, and the injected gas mixture, had an impact on the type and concentration of metals released. The ubiquitous presence of carbonate minerals means that this study is applicable to understanding the potential risk factors for water quality changes, and the mobilization and fate of environmentally regulated metals, in both CO2 storage complexes and overlying drinking water aquifers worldwide.
