Strontium isotopes (87Sr/86Sr) are useful to trace processes in the Earth sciences as well as in forensic, archaeological, palaeontological, and ecological sciences. As very few large-scale Sr isoscapes exist in Australia, we have identified an opportunity to determine 87Sr/86Sr ratios on archived fluvial sediment samples from the …

WebMar 14, 2024 · What we are actually comparing is the mass per unit volume, that is, the density. In order to determine these densities, we might weigh a cubic centimeter of each sample. If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm –3 and that of the soil as 1.20 g cm –3. WebDacite is an extrusive igneous rock composed primarily of feldspar, quartz, and smaller amounts of mafic minerals. It has an aphanitic texture, meaning its interlocking crystals cannot be seen with the naked eye. Dacite comes in many colors but is usually off-white, light gray, or brown and is often porphyritic.
