Triassic tetrapod tracks have long been studied, including classic ichnofaunas such as those of the lower Newark Supergroup of eastern North America and the Bundsandstein of central Europe. They are known from all seven continents and encompass five archetypal vertebrate ichnofacies for nonmarine environments (Chelichnus, Grallator, Batrachichnus, Brontopodus, Characichnos), all of which are pr...

Subduction erosion is widely thought to play a significant role in crustal recycling at modern convergent plate margins. However, identifying subduction fossil accretionary margins difficult due multiple episodes of tectonic superimposition and an absence direct geophysical evidence. By assessing provenance metamorphic records this study, we are the first document record Late Triassic Middle Ju...

Tight sandstone gas (TSG) reservoirs develop extensively in the upper Paleozoic coal bearing strata both southern North China Basin and Ordos Basin. The former has not achieved important advances TSG exploration, while latter built largest production facility China. By comparing accumulation conditions Tongxu area of Fuxian Basin, main controlling factors were analyzed this article. results ind...

Triassic vertebrate tracks are known from the beginning of the 19th century and have a worldwide distribution. Several Triassic track ichnoassemblages and ichnotaxa have a restricted stratigraphic range and are useful in biochronology and biostratigraphy. The record of Triassic tracks in the Iberian Peninsula has gone almost unnoticed although more than 25 localities have been described since 1...

The McLymont property is located close to the headwaters of McLymont Creek, a tributary of the lskut River; it lies at an elevation of approximately I I70 metres (3800 feet), about 2 kilometres southwest of Newmont Lake (Figure 2-l I-l) The property is currently being explored by Gulf International Minerals Ltd. It contains two styles of mineralization whose relationship to each other is uncert...
