Natural cordierite crystals with a range of Mg:Fe ratios have been annealed at a range of temperatures between 1200 and 1430 degreesC (under controlled f(O2)), after previously being annealed at 900 degreesC to drive off any volatiles contained withi

A natural ferromagnesian cordierite which had been annealed at 1355°C has been found, by TEM, to contain submicroscopic cross hatched modulated microstructures (tweed) localised near Al 2 O 3 inclusions, while most of the sample, apart from some mel

Two natural dunites were annealed at pressure P =300 MPa, temperature T =1373, 1473 and 1573 K, and f O 2 within the stability field of olivine. The starting materials contained small amounts of hydroxyls in the form of minor phases of hydrated miner

The metal–silicate microstructures in the shock-induced melt pockets of the Tenham (L6) chondrite have been investigated by analytical transmission electron microscopy. The melt areas, formed under high-pressure, high-temperature dynamic shock cond

Composition profiles have been measured in transformation twin walls of the albite type in anorthoclase. Regions close to the walls between two twin domains are enriched in K and Na and depleted in Ca and Al. Microanalysis experiments show high mobil

A polycrystal sample of Fe-bearing prismatic sillimanite was annealed experimentally at T= 1675°C and P = 20 kbar for 12 min. ATEM investigation of the sample reveals that the starting material partly transformed into mullite during the annealing, a

Four pallasites (Brenham, Brahin, Esquel, and Omolon) were investigated by analytical transmission electron microscopy. All show very similar compositions and defect microstructures. The olivine grains contain a low density of c dislocations organize
