T1 - The Braunschweig meteorite − a recent L6 chondrite fall in Germany N2 - On April 23rd 2013 at 2:07 a.m., a 1.3 kg meteorite fell in the Braunschweig suburb Melverode (52° 13′ 32.19″ N. 10° 31′ 11.60″ E). Its estimated velocity was 250 km/h and it formed an impact pit in the concrete fall site with a diameter of 7 cm and a depth of 3 cm. Radial dust striae are present around the impact pit. As a result of the impact, the meteorite disintegrated into several hundred fragments with masses up to 214 g. The meteorite is a typical L6 chondrite, moderately shocked (S4) – but with a remarkably high porosity (up to 20 vol%). The meteorite was ejected from its parent body as an object with a radius of about 10–15 cm (15–50 kg). The U,Th-He gas retention age of ∼550 Ma overlaps with the main impact event on the L-chondrite parent body ∼470 Ma ago that is recorded by many shocked L chondrites. The preferred cosmic-ray exposure age derived from production of radionuclides and noble gas isotopes is (6.0 ± 1.3) Ma.

T1 - Identification and classification of historical writing inks in spectroscopy: a methodological overview N2 - The identification of the type of ink should be among the primary goals of manuscript description. Several techniques of instrumental analysis are available, and new tools have been appearing on the market, the main development having been to more portability and user friendliness. In this article, we would like to give an overview of several existing methods and of their respective advantages and the results (on the example of a Coptic manuscript) that can be obtained with their help.
