Protoplanetary disks are dust- and gas-rich structures surrounding protostars. Depending on the distance from protostar, this dust is thermally processed to different degrees accreted form bodies of varying chemical compositions. The primordial accretion processes occurring in early protoplanetary disk such as chondrule formation metal segregation not well understood. One way constrain them stu...

Enstatite is a ubiquitous phase in chondritic meteorites, interplanetary dust particles, and cometary samples. In equilibrium condensation models, enstatite predicted to condense via reaction between pre-condensed forsterite gaseous SiO. However, previous studies have shown that some enstatites chondrite matrices AOAs do not genetic relationship with forsterite, arguing against formation by the...

Short life of current total hip replacement metallic implants is generally dependent on the aseptic loosening of the implant, which occurs due to mismatch of elastic modulus between bone and metallic implant materials. Decreasing in elasticmodulus of implant could be successful. Forsterite is biocompatible and bioactive ceramic which has suitable mechanical properties. In presented research the...

Panah Kuh skarn is located about 50 km northwest of Taft City in Yazd province. The intrusion of Panah- Kuh stock with granodiorite-quartz diorite composition into the limestone Jamal Formation has led to the skarnification in this area. Field and mineralogical observations show that Panah-Kuh skarn included two endoskarn and exoskarn zones. Exoskarn is calcic type and magnesian skarn which for...

Determination of  stability limits, mineralogical changes and  thermal reaction of serpentine minerals are very important for the  investigation of magmatism, mechanism and depth of  plates of subduction. During the subduction process, serpentine (Lizardite) minerals will release their water due to thermal reactions. This dehydration can play an important role in volcanism processes related to ...
