thks Opto -pleased that was the case..
More generally however see 'Conclusion' from another paper cited earlier , for the convenience of HC's DRG followers:

"Upper Proterozoic and Paleozoic rocks are interpreted
as offset features which constrain the sense
and amount of displacement on the Gobi Onon,
Tost and Zuunbayan faults. Relative age relationships
of the offset markers and overlying sequences
apparently narrow timing of deformation from the
Triassic to early-Late Cretaceous. Preliminary work
on mylonitized rocks related to one of the three
fault zones, as well as nearby deformed sequences
on all three faults, suggest deformation during the
Late Triassic to Early or Middle Jurassic. More
extensive studies throughout this region, including
additional and more comprehensive coupled
thermochronologic=kinematic analyses of the fault
zones, are needed to clarify slip histories and tectonic
affinities. Understanding the history of faulting
and deformation in southern Mongolia is crucial,
not only to unravel the tectonic history of Mongolia,
but also to address larger questions regarding
the tectonic amalgamation of Asia. This model, although
preliminary, presents testable hypotheses and
implications for faults in China and Mongolia."
