The Buritizal meteorite: classification of a new Brazilian chondrite
On August 14, 1967, the reporter Saulo Gomes, working at TV Tupi, went to a small city in the State of São Paulo called Buritizal to investigate reports of a meteorite fall and write a newspaper report.

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Particle Accretion in Microgravity. I. Particle Sizes and Bulk Densities
The precise mechanisms related to the accretion of protoplanetesimals from dust in protoplanetary disks (PPDs) are poorly understood. In order to better understand the early stages of planet formation and the growth of millimeter–centimeter agglomerates,

ABSTRACT The Transbrasiliano‐Kandi‐4°50′ (TK4) shear zone in western Gondwana crosscuts South America and NW Africa for at least 6000 km. Despite its impressive size, the timing of the main episode of dextral ductile shearing is uncertain. We present detailed in situ multi‐mineral geochronology of mylonites from both Brazil and Algeria supporting that ...

Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

New Zealand's Second Meteorite: Makarewa (find, L4, S5, W2)
One of the most remarkable discoveries of a meteorite in New Zealand was that of Makarewa. Discovered in 1879, Makarewa is a ‘find’ that was uncovered a metre below the surface of a clay bank during excavation works for a train line in the southern South Island.

Chiral Symmetry Breaking in Gelation
Although chiral symmetry breaking in gelation is usually regarded as a rare phenomenon, this might not be true. Rather, recent studies suggest that its probability to emerge in gelation can be higher than that in crystallization, indicating the presence of rich science to be uncovered in the corresponding research fields.
