An Unusual liptinite Coal component has been reported in the Chinese literature over the past sixty years. It has been described as a maceral in the Chinese National Standard (1991), but it has not been named internationally. In Chinese literature it is called "barkinite", on the basis of its morphological features and because it is believed to have originated as bark tissue. "Baxkinite" occurs in Late Permian, marine-influenced coals and is best represented in the Changguang, Leping and Shuicheng Basins of southern China. The material originates from plant periderm or the bark of higher plants. However, "bark" contmns a variety of substances, including resin and suberin, which are recognised as the precursors of the resinite and suberinite macerals, "Barkinite" is distinguished by (i) its thickness; individual pieces Can be more than ten cellS thick and severn centimetres long and (ii) it fluoresces strongly at 0.6% viiinite reflectance and loses its fluorescence at about 1.1% vitrinite reflectance. The reporting of "barkinite" from only Chinese Coals may be due to its origin from Lepidodendron and Psaronius flora, which was common in the Northem Hemisphere duffng the Carboniferous, but which was isolated to China by the Late Permian. It is proposed that the remnant flora evolved into unique forms in China by the Late Permian. Lepidodendrou and Psaronius remains, coupled with a strongly marine-influenced, peat-forming environment have given rise to "barkinite" and to its restricted distribution.
