High-frequency Cycles and High-resolution Sequence Stratigraphy of Ruyang Group, Mid-Proterozoic Era in Western Henan

  • Received Date: 1996-10-21
  • Ruyang Group in the western Henan can be divided into six third-order sequences. These sequences are made of some high-frequency sequence. The sequence 6 in them contains 9 parasequences sets and more than 36 parasequence. A parasoquence consistsof various sedimentary facies having upward-shallowing sequence, and is bounded by hiatus. The grain size is upward-coarseningand bed is upward thicking in parasequence. Geochemical data show As, Sb decrease and &13C increase in upward-shallowing se-quence. The character of the parasequence has relationship with to the sea-level change.

High-frequency Cycles and High-resolution Sequence Stratigraphy of Ruyang Group, Mid-Proterozoic Era in Western Henan

Abstract: Ruyang Group in the western Henan can be divided into six third-order sequences. These sequences are made of some high-frequency sequence. The sequence 6 in them contains 9 parasequences sets and more than 36 parasequence. A parasoquence consistsof various sedimentary facies having upward-shallowing sequence, and is bounded by hiatus. The grain size is upward-coarseningand bed is upward thicking in parasequence. Geochemical data show As, Sb decrease and &13C increase in upward-shallowing se-quence. The character of the parasequence has relationship with to the sea-level change.
