New models,new questions: historiographical approaches to the Romanian Holocaust

This essay surveys the historiography on the Romanian Holocaust, focusing in particular on four monographs published by Western historians within the past five years. Earlier research was limited both empirically and theoretically, and these works suggest new research paradigms and raise new questions about the genocide in Romania during the Second World War. Dennis Deletant assesses the rule of General Ion Antonescu in light of his responsibility for the Holocaust and attempts to explain why the General began and ended the Holocaust when he did. Vladimir Solonari argues that the Holocaust should be read in the context of plans for ethnic homogenisation which were implemented when the opportunity presented itself in 1941. Jean Ancel examines the expropriation of Jewish property and shows that, among other things, the Romanian perpetrators were motivated by a desire to enrich themselves at the expense of the Jews. Finally, Armin Heinen reads the Holocaust by looking at how different groups of perpetrators used violence and attempts to recreate the logic that shaped their actions. In addition, the essay discusses Holocaust denial, survivor memoirs and the state of primary-source collections on the Romanian Holocaust.

Precipitation of lead–zinc ores in the Mississippi Valley‐type deposit at Trèves,Cévennes region of southern France

The Trèves zinc–lead deposit is one of several Mississippi Valley‐type (MVT) deposits in the Cévennes region of southern France. Fluid inclusion studies show that the ore was deposited at temperatures between approximately 80 and 150°C from a brine that derived its salinity mainly from the evaporation of seawater past halite saturation. Lead isotope studies suggest that the metals were extracted from local basement rocks. Sulfur isotope data and studies of organic matter indicate that the reduced sulfur in the ores was derived from the reduction of Mesozoic marine sulfate by thermochemical sulfate reduction or bacterially mediated processes at a different time or place from ore deposition. The large range of δ³⁴S values determined for the minerals in the deposit (12.2–19.2‰ for barite, 3.8–13.8‰ for sphalerite and galena, and 8.7 to ?21.2‰ for pyrite), are best explained by the mixing of fluids containing different sources of sulfur. Geochemical reaction path calculations, based on quantitative fluid inclusion data and constrained by field observations, were used to evaluate possible precipitation mechanisms. The most important precipitation mechanism was probably the mixing of fluids containing different metal and reduced sulfur contents. Cooling, dilution, and changes in pH of the ore fluid probably played a minor role in the precipitation of ores. The optimum results that produced the most metal sulfide deposition with the least amount of fluid was the mixing of a fluid containing low amounts of reduced sulfur with a sulfur‐rich, metal poor fluid. In this scenario, large amounts of sphalerite and galena are precipitated, together with smaller quantities of pyrite precipitated and dolomite dissolved. The relative amounts of metal precipitated and dolomite dissolved in this scenario agree with field observations that show only minor dolomite dissolution during ore deposition. The modeling results demonstrate the important control of the reduced sulfur concentration on the Zn and Pb transport capacity of the ore fluid and the volumes of fluid required to form the deposit. The studies of the Trèves ores provide insights into the ore‐forming processes of a typical MVT deposit in the Cévennes region. However, the extent to which these processes can be extrapolated to other MVT deposits in the Cévennes region is problematic. Nevertheless, the evidence for the extensive migration of fluids in the basement and sedimentary cover rocks in the Cévennes region suggests that the ore forming processes for the Trèves deposit must be considered equally viable possibilities for the numerous fault‐controlled and mineralogically similar MVT deposits in the Cévennes region.
