Quality Assurance and Quality Control is a guide for private and public companies- https://shorturl.at/M30sJ Exploring Geological Data with WEKA, CodaPack, and iNZight - https://shorturl.at/pr7u8 Systematics of the Magmatic Processes- https://shorturl.at/0IhNY Valls' book on Quality Assurance and Quality Control is a guide for private and public companies on how to implement these programs. The book includes information on: The definition of quality assurance and quality control. Designing a quality assurance/quality control program. The types of quality control samples, including duplicate samples, blind samples, blank samples, and standard controls. Implementing field programs, such as how many quality control samples to take. Testing the quality of the quality control program. Procedures for drilling programs. A system for naming rocks and alteration in the field. Flow charts to determine appropriate names for rocks. An atlas of alteration and its relation to different types of deposits. Valls' book, Exploring Geological Data with WEKA, CodaPack, and iNZight, is a step-by-step guide on how to use these three programs to process geological data. The book focuses on: Machine learning and artificial intelligence, which are becoming popular in geology. Weka, a free online resource for machine learning developed by the New Zealand University of Waikato. CodaPack, a free software for compositional data analysis. iNZight, a free program for data visualization, including three-dimensional representations and integration with Google Earth. Valls' book Systematics of the Magmatic Processes is a comprehensive resource for senior geologists studying magmatic metal aromatic rocks. This book covers: The theory and basic knowledge of magmatic processes and related deposits. A description of assays and experiments that can be performed on rocks. How to process and work with chemical data. Field identification of rocks. Quality assurance and quality control in a magmatic environment. Basic geometrical modeling of data to determine distribution laws. The concept of compositional data analysis. Real-world case studies from around the world. How to identify the most probable magmatic process, such as melting, crystallization, partial or fractional crystallization, mixing, and contamination. Appendices with useful tables and descriptions of results. P. Geo. Ricardo A Valls, M.
