My answer may not be correct, but we found such a flow structure recently in a calcite-rich rock. We just called it "intrusive" for now.

I asked a question about this earlier today, looking for people who have seen similar structures.

Dear Asoori Latha,

I do not think there is specific literature on this subject. Below I indicate a reference where descriptions of flow texture in carbonatite, related to magnetite are included.

Boniface (2017) Crystal chemistry of pyrochlore from the Mesozoic Panda Hill carbonatite deposit, western Tanzania. Journal of African Earth Sciences 126, 33-44.

I can send you a PDF if you cannot access the magazine.

Artur

Thanks a lot for the valuable answer.
