Dorrite (original) (raw)
La dorrita és un mineral de la classe dels silicats, que pertany al grup de la rhönita. Rep el nom en honor de John A. "Jack" Dorr, Jr. (1922/3 - 8 d'abril de 1986), professor de geologia de la Universitat de Michigan, EUA, en reconeixement a la seva investigació geològica a l'estat de Wyoming.

| dbo:abstract | La dorrita és un mineral de la classe dels silicats, que pertany al grup de la rhönita. Rep el nom en honor de John A. "Jack" Dorr, Jr. (1922/3 - 8 d'abril de 1986), professor de geologia de la Universitat de Michigan, EUA, en reconeixement a la seva investigació geològica a l'estat de Wyoming. (ca) Dorrite is a silicate mineral that is isostructural to the aenigmatite group. Although it is most chemically similar to the mineral [Ca2Mg5Ti(Al2Si4)O20], the lack of titanium (Ti) and presence of Fe3+ influenced dorrite's independence. Dorrite is named for Dr. John (Jack) A. Dorr, a late professor at the University of Michigan that researched in outcrops where dorrite was found in 1982. This mineral is sub-metallic resembling colors of brownish-black, dark brown, to reddish brown. (en) Dorrita silikato motako minerala da eta rhönite taldearen kidea da. (eu) La dorrite è un minerale.
