This Open Access book introduces readers to the regional geology of
Hanggai, Xianxia and Chuancun, the area between China's northern
Zhejiang Province and southern Anhui Province and explores the
strata, magmatic rocks and tectonic structures in 1:50,000 scale
geological maps. Based on studies of multiple stratigraphic
divisions, the standard stratigraphic section of the upper
Ordovician Hirnantian in the lower Yangtze region is established,
revealing for the first time numerous "Burgess Shale-type" sponge
fossils in Hirnantian strata and identifying 10 grapholite fossil
belts and various fossil categories, including chitin, trilobites,
gastropods, brachiopods, and cephalopods. Moreover, the book
identifies for the first time Late Ordovician volcanic events in
northern Zhejiang province. The work represents a major
contribution to research on Paleozoic strata in the Lower Yangtze
region, and sheds new light on understanding the Hirnantian glacial
event and biological extinction event in South China by providing a
high-precision time scale. In addition, the book opens an important
avenue for future research on sponge evolution after the Cambrian
life explosion. As such, it offers a unique and valuable asset for
researchers and graduate students alike.
