Estuarine sandstone thin section slide exhibiting a range of features characteristic of this diverse and complex depositional setting. Hand specimens reveal a largely fine grained sediment however the thin section shows that the sediment is not as homogeneous as it appears with the naked eye. Grain size varies quite significantly, clasts are rounded to angular, composed of a range of different minerals and lithic fragments. The thin section supplements the hand specimens nicely and offers an opportunity to interpret the complex transportation and depositional process of this sediment, perfect for educational use. This material was collected from Carboniferous strata in Yorkshire, UK. The thin section is made to 30 microns thickness and the glass is 46 x 27 mm in size with a cover slip. Supplied in a protective card sleeve with a label, ideal for microscopy.
