Stratigraphic Model of East Biak Based on Magnetotelluric Data

open access: yesJournal of Mathematical and Fundamental Sciences, 2020
Biak Island is thought to have originated from the Australian Continental passive margin in the Mesozoic. This passive margin underwent tectonic collision to form the bedrock of Biak Island during the Paleogene.

Ordovician sequence stratigraphy and correlation in the Middle-Upper Yangtze region, South China

open access: yesChina Geology, 2018
: The precise correlation of the Ordovician successions in different facies is difficult due to the complex changes of the tecto-paleogeography in South China. Based on previous studies, the authors recognized 10 3rd grade sequences, i. e., Osq1 to Osq10

Stop 2 Kainui silt loam and Naike clay, Gordonton Rd [PDF]

open access: yes, 2008
At this stop are several remarkable features both stratigraphic and pedological, and a “two-storied” soil, the Kainui silt loam alongside (in just a few places) the Naike clay. Both soils are Ultisols. The sequence of tephra beds and buried soil horizons
