X-ray diffraction data for heat treated samples of hydrothermal minerals from seamounts within the Tuvalu Exclusive Economic Zone A sample of hydrothermally mineralized foraminifera ooze (D28A) was collected via dredge from a seamount within the Tuvalu Exclusive Economic Zone in the Pacific Ocean during cruise RR1310 funded by the National Science Foundation aboard the R/V Roger Revelle in 2013. USGS scientists requested these ferromanganese crust samples from the Oregon State University Marine and Geology Repository where they had been archived. Ferromanganese crust samples were sent to USGS for subsampling and x-ray diffraction analyses. Powder x-ray diffraction data for three layer-fractions of the hydrothermal sample are provided here. Measurements were made after heating to 115 C for 48 hours to test the stability of the phyllomanganate...

The original collection of 169 reference diffractograms was released by Eberl (2003) as a part of RockJock, a USGS program for quantitative analysis of mineralogy, which included patterns of many of the major rock-forming minerals needed to analyze a wide variety of rocks, sediments, soils, and other geologic materials. The library was generated from mineral samples collected from the environment or synthesized in the laboratory. In the case of geologic samples, every effort was made to collect as pure a mineral specimen as possible. The purpose of this data release...

Gaining a better understanding of the formation mechanisms for these deposits is critical for defining proper exploration criteria in gold-bearing regions and production within these deposits. Monazite are light rare earth (LREE)-bearing and xenotime are heavy rare earth (HREE)-bearing phosphate minerals that are found as alteration products in many gold deposits. In addition to their importance in geochronological investigations, their minor element chemistry may be used to differentiate between metamorphic, magmatic,...
