Cretaceous strata are widely distributed across China and record a variety of depositional
settings. The sedimentary facies consist primarily of terrestrial, marine and interbedded …

Correct selection and interpretation of proxies are key to cyclostratigraphic research;
however, the uncritical use of geophysical logs as proxies for cyclostratigraphy could be …

The lacustrine shale of the Upper Cretaceous Qingshankou Formation is the principal
prospective unconventional target lithology, acting as source, reservoir, and seal. Lithofacies …

The time scale for marine magnetic anomalies for the Late Cretaceous through Neogene (C-
sequence) and Middle Jurassic through Early Cretaceous (M-sequence with deep-tow …

Earth's climate system is complex and inherently nonlinear, which can induce some
extraneous cycles in paleoclimatic proxies at orbital time scales. The paleoenvironmental …

Over the past 25 yr, the science of stratigraphy has evolved to include time-correlative data
from vastly disparate components of the Earth system. Not least of these is the global signal …

In ancient hothouses lacking ice sheets, the origins of large, million-year (myr)-scale sea-
level oscillations remain a mystery, challenging current models of sea-level change. To …

The early Cambrian was a critical period of Earth history, marked by explosive diversification
of metazoans and several profound changes in Earth's surface environments and global …

The Earth's geologic record of Milankovitch cycles closely tracks Solar System solutions for
the past 50 million years. Prior to 50 million years ago (Ma), however, the solutions lose …

An important innovation in the geosciences is the astronomical time scale. The astronomical
time scale is based on the Milankovitch-forced stratigraphy that has been calibrated to …
