Looks like AGV-2 might no longer be available per the USGS GGGSC. #Geology folks who do whole-rock #ICPMS #geochem, what are your preferred #SRM's these days for igneous #rocks?

USGS Geochemical and Microanalytical Reference Materials Distribution | U.S. Geological Survey

The Geology, Geophysics, and Geochemistry Science Center distributes geochemical reference materials and microanalytical reference materials. Reference materials are suitable for use in testing analytical methodologies and as quality control samples.

Might have been excessively ambitious for a #geochemistry course redesign, now realizing I need to actually plan the course!

Have favorite ideas, #textbooks, #tutorials, #resources, to share?

The details:
1. Upper-level #undergrad #SLAC #geochemistry course, but no rigid pre-reqs (start with #basics).

2. Would like to build course around using #R #Rstats to make #geochemical #plots! I'm also an #Rnovice, though, so I'll also be learning as we go.

3. Includes #lowT and #highT #geochem.

How much arsenic, selenium, and lead is in these lake sediments from California’s receding #SaltonSea? That’s the research question for these environmental geochemistry undergrad students at #UniversityofSanDiego

Newbie here, trying out a post with pics. Here’s my geochem class doing some water and sediment sampling at the #SaltonSea last week. That truck/ute is actually bogged in this pic 😆 #EnvironmentalHealth #Geochem
