Student Project: Explore Rocks Using Core Sampling

2021-2-26  A core sample is a long narrow piece of rock obtained by drilling into a rock with a special tool that lifts out an intact part of the rock. In-depth study of core samples requires a science lab full of equipment – something we don’t yet have on Mars. So, we must return these samples to Earth for study.

2021-6-26  Though I agree by crushing the whole core the sample will be more representative, crushing the whole core should be avoided for the purposes of transparency. By keeping a half core as it came from the core barrel any consultant or QA/QC representative will understand the style and structure of the mineralization being sampled.

Sample Preparation the First Step of Successful Research

2020-2-27  Sample preparation involved two major processes: crushing rock chips and exchanging surface cations. Each of these processes will be discussed separately. The first step in analyzing the unfrozen water mass and mobility in frozen soil 1was to procure fine-grained soil samples. We developed a method for crushing the rock chips

Drill Core Sampling and Sample Preparation AKA

2021-6-21  (The primary assay samples are ½ core.) The (½) core is crushed to -2mm as part of sample prep, and the precision of duplicate samples at this stage improves dramatically. Of course ½ core needs to be retained for future geological reference so submitting all core for chemical assay to improve precision is not an option.

2021-6-21  If you take 2 sub-samples from crushed 1/2 core you observe a duplicate variance. If you take 2 similar sub-samples (with same sample mass) from the entire crushed core, you will have a LARGER duplicate variance due to the factor (1/MS - 1/ML), MS being the sample mass (not changed) and ML being the lot mass (doubled when the lot is the entire core compared to the 1/2 core).

Evaluation of size reduction process for rock

2020-6-4  The core samples were placed in a desiccator filled with distilled water for 24 h (Fig. 3b). A vacuum pump was used to reach an effective saturation of rock materials. Following the immersion of the core samples, the saturated mass of each core sample was measured. Then, the core samples were placed in a drying oven at 105 ± 2 °C for 24 h.
