Complex peridotite body, with three peridotite suites :
1) Harzburgite / lherzolite suite
2) Banded dunite / harzburgite suite (cumulate)
3) Spinel-rich dunite / wehrlite suite (cumulate)
The structure of the peridotite body is layered, two main zones have been distinguished :
- Upper zone (600 meter thick) : Core of an ascending mantle diapir (with thermal gradient), with plagioclase lherzolites and harzburgites, and mafic layers.
- Lower zone (2200 meter thick) : Margin of an ascending mantle diapir, with cyclic layers plagioclase lherzolite/lherzolite/harzburgite/dunite/harzburgite/lherzolite/plagioclase lherzolite (with mafic layers).
The garnet peridotite (830 Ma) grades into a plagioclase peridotite during ascension.
The Horoman peridotite is a MORB-related oceanic mantle subsided to deeper mantle depth, before crustal ascension and emplacement (23 Ma).
