Abstract
We present an analytical review of the key results and research trends in the Deep Carbon Cycle program. The first section addresses the issues related to subduction zones with emphasis on geological and geophysical data on Kamchatka and the Kokchetav paleosubduction zone. Experimental studies over a wide pressure range are discussed in the section “Crystallogenesis and experimental mineralogy”. The papers addressing the diamond issues on the example of the Yakutian diamondiferous province are grouped in the sections “Diamond crystallogeny” and “Diamond and kimberlite magmatism”.
