摘要

攀家坝地区位于龙门山—大巴山成矿带内，成矿地质条件优越，找矿潜力巨大，是我国多类型矿床的重要地区。通过对潘家坝地区1:25万土壤地球化学资料的分析，采用地层分带异常下限对比法识别异常。该方法有效地缓解了地层背景变化，最大限度地减少了地层对异常识别的影响，为勘探活动提供了有价值的信息。通过异常验证和挖沟工作，在该区发现了2个含金蚀变带和8个金矿化体。研究强调了地层分带异常下限对比方法在复杂地层地区的有效性，并表明其在类似地质环境中的广泛适用性。

Gold geochemical anomalies delineated by the stratigraphic zoning anomaly lower limit contrast method: a case study of panjiaba, Shaanxi province, China.

The Panjiaba area, situated within the Longmenshan-Dabashan metallogenic belt in Shaanxi, Northwestern China, is a significant region for various deposit types due to its favorable metallogenic geological conditions and exploration potential. By analyzing 1:25,000 soil geochemical data from the Panjiaba area, anomalies were identified using the stratigraphic zoning anomaly lower limit contrast method. This method effectively mitigates stratigraphic background variations, minimizing the influence of stratigraphy on anomaly identification and providing valuable information for exploration activities. Subsequent anomaly validation and trenching efforts led to the discovery of two gold-bearing alteration zones and eight gold mineralization bodies in the area. The study underscores the efficacy of the stratigraphic zoning anomaly lower limit contrast method in regions with complex stratigraphy and suggests its broad applicability in similar geological settings.

期刊介绍： We publish original research from all areas of the natural sciences, psychology, medicine and engineering. You can learn more about what we publish by browsing our specific scientific subject areas below or explore Scientific Reports by browsing all articles and collections. Scientific Reports has a 2-year impact factor: 4.380 (2021), and is the 6th most-cited journal in the world, with more than 540,000 citations in 2020 (Clarivate Analytics, 2021). •Engineering Engineering covers all aspects of engineering, technology, and applied science. It plays a crucial role in the development of technologies to address some of the world''s biggest challenges, helping to save lives and improve the way we live. •Physical sciences Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature — often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics. •Earth and environmental sciences Earth and environmental sciences cover all aspects of Earth and planetary science and broadly encompass solid Earth processes, surface and atmospheric dynamics, Earth system history, climate and climate change, marine and freshwater systems, and ecology. It also considers the interactions between humans and these systems. •Biological sciences Biological sciences encompass all the divisions of natural sciences examining various aspects of vital processes. The concept includes anatomy, physiology, cell biology, biochemistry and biophysics, and covers all organisms from microorganisms, animals to plants. •Health sciences The health sciences study health, disease and healthcare. This field of study aims to develop knowledge, interventions and technology for use in healthcare to improve the treatment of patients.
