Ting-Ying H. Ma
Formula:
Ca18(Ca,◻)2Fe2+2(PO4)14
Crystal System:
Trigonal
Name:
Named in honor of Ting-Ying H. Ma (馬廷英) (1899, County Jin, Liaoning Province, China - 15 September 1979, Taipei, Taiwan), professor and palaeontologist. He studied coral growth and sea water temperature, with implications for palaeoclimatology and tectonics. He was director of the Department of Geology and the Institute of Oceanography of National Taiwan University (1946-1950).
Reported as a member of merrillite group. The Ca analogue of ferromerrillite and Mg analogue of keplerite. First anhydrous purely Ca-Fe phosphate mineral.
