Coring The Basalt Joides Resolution Method: custom designed core bits with discrete cutters (polycrystalline diamond or pdc elements) were used to drill high strength basalt rock under conditions of low temperature and pressure. Therefore, to effectively implement the large depth icp coring in an extreme lunar environment, the primary task is to select lunar rock simulant from earth and test them to elucidate the thermal physical properties of lunar rock simulants under extreme conditions.
Home Page Basalt International The three sites with the highest coring rates on figures 3 and 4 were reported to consist either of highly vesicular basalt or of basalt which was judged to have been extruded at relatively shallow depths. We report and evaluate drilling results in hard basalt under mars low pressure conditions and introduce an equation that may be used to estimate drilling performance in hard formations. In several cases, significant modifications to equipment were designed and fabricated on board ship. this was the first successful coring of near "zero age" basalt in volcanic terrain on the seafloor. a hole 79 m deep was cored with significant recovery and no problems with side wall stability. This led to a custom coring tool design which incorporated coring, core breakage, core retention, and core extraction functions. the coring tool was tested on several types of rock and demonstrated the overall feasibility of this approach for robotic rock sample acquisition.

Wireline logs were acquired at seven sites in the newark rift basin using dipmeter, gamma ray, resistivity, velocity, porosity, density, magnetic susceptibility, temperature, and acoustic televiewer tools. the logs indicate that the formations are clay rich and dip on average 9°n nw. Also studied are the coring forces that develop while using a pcd compact core drill to penetrate basalt rock. extensive data were collected on thrust force and torque under a variety of coring parameters as well as two basalt rock formations: one relatively ‘soft’ and the other relatively ‘hard’. Current fixed cutter bits for coring hard rocks such as basalt include diamond impregnated and diamond surfaceset bits, in which many generally rounded and more or less randomly placed diamonds project out of the surface of a metallic matrix (figure 1).
