Sample Heated by CO2 Laser Under Ultra-High Vacuum
Groundmass basalt sample is being heated by a CO2 laser, glowing red-orange while releasing Argon gas to be measured for 40Ar/39Ar Geochronology.

Our first instrument is a Mass Analyser Products (MAP) Model 215-50 mass spectrometer that is a single-collector 90° sector instrument with a Nier-type source. This system is equipped with a Heine low-blank, double-vacuum resistance furnace and a first-generation Merchantek MIR10-TP integrated CO2 laser gas extraction...

Our second instrument is an Thermo Scientific Model ARGUS VI multi-collector mass spectrometer with five fixed Faraday detectors (including amplifier circuits with 1012 Ohm resistors) and one ion-counting CuBe electron multiplier mounted next to the low mass 36 Faraday detector. This system is equipped with an 25 W Synrad CO2 laser with industrial scan head for carrying out gas...

IODP Expedition 330 to the Louisville Seamount Trail drilled five underwater volcanoes off the NE coast of New Zealand. One hypothesis states that these volcanoes formed above a narrow plume of hot mantle rising from a position deep in the Earth’s mantle. For decades scientists assumed these mantle plumes remain anchored there for tens of millions years, but there is mounting evidence that...
