Petroleum Source Rocks, Generation and Primary Migration: insights using new direct nano-scale Tof-Sims SEM analysis and Re-Os radiometric dating
- Publication Name: AEGC 2021
- Authors: Greg Smith, William Rickard, Zhen Li, Svetlana Tessalina
- Date Published: September 2021
Abstract:
Exactly how maturation, generation and primary migration in and from source rocks works at the nano-scale remains largely a mystery. The theories and concepts rely mostly on destructive analytical techniques that by their nature do not allow direct o...
