This includes the location of the sites, their lithology and the techniques of sampling from these sites. It shows that Bringelly Shale contains more reactive clay minerals and is more weakly cemented than Ashfield Shale. [2] The chemistry of the rock is typical of shales, with high iron levels, and some iron sulphide and low calcium levels. However, there is little evidence of induration and only apparently weak bonding due to recrystallisation of mica at particle contacts. At some locations, where the Ashfield Shale overlies or is immediately up gradient of the Hawkesbury Sandstone, saline groundwater from this aquitard contributes to the higher salinities observed in the upper part of the sandstone (Webb et al. William; David W. In this formation originated in the Triassic Bändertone and mudstones, which contain a few small sandstone deposits. However, William and Airey (2009) showed in their study on Bringelly shale that depending on the degree of cementation of a shale, it can also be sufficient to compact the remoulded material to Jun 1, 1986 · The Bringelly Shale, containing claystone, siltstone and laminite, with some sandstone beds, overlies Ashfield Shale in the study area.
