Sample Specifications
Sample Specifications
Apatite and Zircon
The ideal minimum number of >20 µm-diameter apatite and zircon grains required for the above methods is about 200. We can work with less and prefer more.
Outcrop Sample
1 kg of granite or granodiorite sample, or equivalent is ideal. For most samples, 250-500 g is sufficient but 1 kg allows for multiple mineral separations of poor-yield samples.
Drill Core
1 kg of sandstone sample, or equivalent is ideal. For most samples, 250-500 g is sufficient but 1 kg allows for multiple mineral separations of poor-yield samples.
Drill Cuttings
1 kg of sandstone sample, or equivalent is ideal. For most samples, 250-500 g is sufficient but 1 kg allows for multiple mineral separations of poor-yield samples.
