survey the earthThere were many ways to survey Earth. The following were some common methods:
###I. Geophysical Exploration
1. ** Principle **
- Geophysical exploration was a method to explore underground minerals and study geological structures using physics principles. The rock (ore) or geological structure that exists underground will have corresponding physical phenomena reflected on the surface or near the surface based on its physical properties, size, and location.
- It uses appropriate instruments to measure and receive various physical phenomenon information in the work area, and applies effective processing methods to extract the required information. According to the difference between the rock (ore) body or the structure and the surrounding rock, combined with the geological conditions to analyze and make a geological explanation.
2. ** Multi-solution and solution **
- Geophysical exploration has multiple solutions because it is an inverse problem of the gravitational field based on the measured data or the observed gravitational field. The inverse result is generally multi-solution.
- In order to obtain more accurate and effective interpretation results, it is generally possible to use a variety of physical exploration methods to carry out a comparison study. At the same time, it is important to combine it with geological survey and geological theory research to carry out comprehensive analysis and judgment.
3. ** Geophysical Field related **
- Geophysical fields can be divided into naturally existing ones (such as the Earth's gravity field, geomantic field, terrestrial electric field, ground temperature field, nuclear physical field) and artificially excited ones (such as the elastic wave field produced by artificial explosion, the local electric field produced by underground power supply, and the electromagnetic field excited by underground electromagnetic waves).
- Geophysical fields can also be divided into normal fields and abnormal fields. Anomaly field is a local geological field caused by the exploration target. Geophysical exploration is based on the distribution characteristics of normal field and anomaly field for geological interpretation and inference. For example, the magnetic field produced by the magnetite ore body or magnetic rock mass underground belonged to the abnormal field, and the difference in density between chromite and surrounding rock would cause abnormal phenomena in the gravitational field.
4. ** Category **
- ** According to rock physical properties **: Commonly used rock physical properties include density, magnetic conductivity, electrical conductivity, elasticity, thermal conductivity, and radiation. The corresponding exploration methods include gravity exploration, magnetic exploration, electrical exploration, earthquake exploration, ground temperature exploration, and nuclear exploration.
- ** According to the measurement space location and area **: It can be divided into surface geological exploration, aerial geological exploration, marine geological exploration, drilling geological exploration, etc.
- ** According to the research object **: It can be divided into metal geological exploration, oil geological exploration, coal geological exploration, water geological exploration, engineering geological exploration, and deep geological exploration.
###II. Geochemical Exploration
- The geological survey was also a way to survey the Earth. However, the reference materials did not elaborate on the specific operations of the exploration of the Earth, but it was included in the scope of the geological survey profession, indicating that it had a unique significance in the exploration of the Earth.
###3. Drill Project
- For example, the Soviet Union's Kola ultra-deep drilling project began in 1970 with the goal of exploring the depths of the Earth. However, due to technical and environmental difficulties, it was stopped in 1993 and finally dug to 12262 meters. Although it failed to break through the Mohorovic Discontinuity between the Earth's crust and mantle, it also revealed some of the secrets of the Earth.
- During the drilling process, information such as rock samples at different depths underground could be directly obtained, which would help to understand the material composition and structure of the Earth's interior. However, the drilling project faced many challenges, such as the high temperature and high pressure environment faced by ultra-deep drilling. It required special drills and technology to deal with it, and it also cost a lot of money, manpower, and other resources.
