Abstract: Provided herein are methods for identifying a region of a geologic area comprising a fault or other feature associated with a pressure loss. Such methods can comprise (1) subjecting rock samples from separated sites in an area to condition(s) that can cause the release of carbon dioxide (CO2), one or more volatile carbon dioxide-related, or both, if present, while not causing the release of a significant amount of CO2 or the one or more CO2-related compounds associated with the crystalline structure of the material, (2) measuring the amount of CO2, the one or more related compounds, or both, and (3) identifying regions in the geologic area associated with a relatively low CO2, related compounds, or both, or similar or alternative methods involving the analysis of such compositions associated with materials provided here.

Abstract: A system for determining residue coverage of a field includes a LiDAR sensor configured to emit light-based output signals for reflection off of a field surface of a portion of a field and detect reflections of the light-based output signals as return signals. Furthermore, the system includes a soil moisture sensor configured to generate soil moisture sensor data indicative of a soil moisture content of the portion of the field. Additionally, a computing system is configured to receive LiDAR sensor data associated with the return signals detected by the LiDAR sensor. Moreover, the computing system is configured to determine a soil moisture value for the portion of the field based on the soil moisture sensor data. In addition, the computing system is configured to determine a residue coverage value of the portion of the field based on the determined soil moisture value and the LiDAR sensor data.

Abstract: A rock testing system includes a rock sample having organic matter provided on a stand in a testing device and a photothermal laser that emits a selected wavelength corresponding to an absorption peak of the organic matter. Methods for testing the rock sample include irradiating the rock sample with the photothermal laser to selectively heat the organic matter and monitoring porosity of the rock sample as the organic matter is heated.

Abstract: Disclosed is a rapid load test method for a pile by use of a method resulting from extending a well-known SULP method, wherein a rapid load test is implemented on a pile head more than once in the manner of changing a drop height h of a weight, with the pile instrumented with strain gages and accelerometers at more than one depth level, followed by the processing of obtaining a rapid load Frapid-pile displacement w relation for each pile segment for each time of the rapid load test using measurement data measured by the strain gages and the accelerometers, of obtaining a soil resistance Rsoil-pile displacement w relation on each pile segment for each time of the rapid load test, of calculating an unloading point that can be a point of maximum displacement of the pile, together with an unloading point load RULP at that moment, and of obtaining a static soil resistance Rw-pile displacement w relation on each pile segment by use of an Unloading Point Connection method using the calculated unloading point and unloading point load RULP for each time of the rapid load test. Accordingly, an analysis on a load-displacement relation is performed by use of a load transfer method with respect to the whole pile, using a nonlinear model of the thus obtained soil resistance on each pile segment.

Abstract: There are provided an optical probe and method for analysing a soil located in an underground area. The optical probe includes a probe head insertable into the underground area to contact the soil, the probe head including a waveguide having opposite first and second ends both optically shielded from the soil; a light source configured to generate a multiwavelength interrogating beam and optically coupled to the first end of the waveguide so that the multiwavelength interrogation beam is inputted in the waveguide to propagate towards the second end; and a detector optically coupled to the second end of the waveguide to detect said multiwavelength interrogation beam. The waveguide includes an unshielded interaction zone extending between the first and second ends providing a wavelength-dependent attenuation of the multiwavelength interrogation beam through interaction with the soil.

Abstract: In a method for discriminating deposit types by using tourmaline elemental components, contents of Sn, Li, Ga, and V trace elements are determined by collecting hydrothermal tourmaline samples in a deposit, and deposit type discrimination is performed with F1, F2, and F3 as discriminant factors, in combination with the characteristics that a porphyry type Cu—Mo—Au deposit has lower contents of Sn+Li, and further, a porphyry type Cu—Mo deposit has higher contents of Ga*V, while a porphyry type Au deposit has relatively low contents of Ga*V; a granite-related Sn—W deposit has relatively high contents of Sn+Li; while an IOCG deposit has relatively high contents of Sn+Li and Ga*V, realizing quick discrimination of the deposit types during prospecting and exploration, shortening the exploration period and reducing the exploration cost, and the method can be used for identification of 4 different types of deposits.
