In order to constrain the minimum age of the Ulan-Sar’dag ophiolite mélange, a whole rock sample (VSK-17-19) was taken from a gabbro–diabase dike by cutting it for 40 Ar/ 39 Ar step-heating dating. The dating was performed by 40 Ar/ 39 Ar by step heating. The obtained age and Ca/K spectra of the sample are shown in Figure 6.

Coarsely crystalline mafic rocks, commonly referred to as dolerite and diabase, make up a substantial proportion of Archean greenstone belts and are hosts to major orogenic gold deposits, yet their internal architecture and contact relationships remain poorly documented and their emplacement origins are assumed rather than supported with evidence.

Diabase is composed of plagioclase feldspar (mostly labradorite) and pyroxene ().The crystals that make up dolerite are usually visible to the naked eye, but sometimes porphyritic rocks of basaltic composition with pyroxene and especially plagioclase phenocrysts are also named that way. Ophitic texture (randomly oriented plagioclase laths enclosed by pyroxene grains) is a characteristic
