Research progress on marine oil and gas accumulation in Tarim Basin

Shiyou shiyan dizhi, 2020
In recent years, great achievements have been made in the exploration of ultra-deep marine oil and gas in the Tarim Basin. New oil and gas discoveries have been achieved in the Shunbei Ordovician, Tazhong Cambrian and Tahe deep strata, which provide ...

Engineering the Cambrian explosion: the earliest bioturbators as ecosystem engineers [PDF]

, 2017
By applying modern biological criteria to trace fossil types and assessing burrow morphology, complexity, depth, potential burrow function and the likelihood of bioirrigation, we assign ecosystem engineering impact (EEI) values to the key ichnotaxa in ...

The recruitment and retention of teachers of colour in Wales. An ongoing conundrum?

The Curriculum Journal, Volume 34, Issue 1, Page 118-137, March 2023., 2023
Abstract There are a disproportionate number of teachers of colour (ToC) in Wales in comparison to pupils of colour. Teachers are less ethnically diverse than the pupils they are teaching with only 1.3% of teachers categorising themselves as being from a non‐White background.

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]

, 2001
The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.
