Back to top: Strata sequence for Unit J1
Introduction
The strata definition currently in use is labeled J1A, and was established in September 2009 and updated in October 2011. Previously the JPA sequence was used, established in August 2007. The J1A sequence refers to J1 and it is based on the J1 data. The current J1A sequence corrrelates to the JPD sequence for the overall JP area.
