美国ZONGE公司GDP 32II型多功能电法工作站
随着地质勘查、矿产开发业的飞速发展，为了满足基础地质调查、矿产资源勘查、水文地质、工程地质、环境地质等领域工作不断向纵深发展的需要，解决攻深找盲及工程深部勘查问题，陕西省地质调查院斥资200万元引进了美国ZONGE公司GDP-32II多功能电法工作站。
GDP-32II多功能电法工作站是一个万用的、多通道的设备，可采集处理任何类型的电磁或电场数据，具有多功能、大功率、高度计算机化、高精度和强抗干扰能力等特点。系统配备有丰富的数据处理软件系统，CSAMT反演解释软件具有地形校正推断解释结果的功能，其二维反演软件具有世界领先水平，很好地将测量勘查数据转化为图形和计算机模型，图形软件包可绘制各种数据曲线图、平剖图、等值线图（拟断面图、平面图等）及三维立体图等。
GDP-32II多功能电法工作站获取不同地层的电性参数，从其差异性来判定、划分地质体，查明地下地层的结构及分布情况，能较好地查明探测区深部隐伏的地质构造情况。主要应用于金属、非金属矿产勘查、工程地质（大坝、铁路、公路等）勘查、石油和天然气勘探、地热资源调查、地下水调查与监测、煤田地质勘查等勘查领域。其勘查有效深度可达2000余米。
2008年9月4-12日，陕西省地质调查院对引进的GDP-32II多功能电法工作站进行了检查验收，并对GDP-32II电法工作站系统涉及的CSAMT、TEM、NanoTEM及IP等方法进行了的野外实际应用测试。同时由香港赛诺技术公司对该系统的软、硬件操作、解释软件等进行了技术培训，通过培训相关技术人员已掌握了该系统的软、硬件操作和相关地球物理数据测试、处理方法，完成了试验区内各项电法参数测定、成图、解释等工作，取得了很好的试验成果。

Zonge Engineering and Research Organization, Inc.
Zonge is a specialist in the development and application of broadband electrical and electromagnetic methods.

For more than 30 years Zonge Engineering and Research Organization has been a leader in the development and application of geophysical methods to subsurface imaging. Starting with minerals exploration in the 1970's, Zonge has since expanded into hydrological, hydrocarbon, environmental, engineering, and unexploded ordnance applications and extended our capabilities to include potential field and seismic surveys.

Zonge's success has been the result of a continuous commitment to the development of new geophysical tools and the integration of the Engineering and Field Service groups, leading to effective and innovative tools. The development of the receiver and transmitter systems has resulted in adaptation of these tools to numerous new applications and created the most versatile electrical and EM receivers available in the world today. This commitment to innovation has led to a series of geophysical firsts:

The first full reference Complex Resistivity measurements
The first battery powered digital IP receiver
The first commercial CSAMT surveys
The first microsecond resolution TEM system
The first fully digital TDEM Unexploded Ordnance detection system
An employee-owned small business, Zonge Engineering and Research Organization integrates research and development programs, equipment manufacturing, and field services. The integration of these roles allows Zonge to provide their clients complete and innovative solutions to their geophysical problems.
