Strata sequence for Unit J7

Caitlin Chaves Yates – January 2012

Introduction
The strata definition chart (JPD - J7)

Introduction

The strata sequence currently used is based on the overall sequence of JPD, concieved during the September/October 2011 study season. The strata assignments are rooted in the materials from J2 and the J2B sequence can be found here. The previous sequence used in J7, was sequence J2A -adapted for use in J7. That sequence can be found here. The complete sequence linked to J2 is preserved here with the relevant strata in J7 indicated in bold.
