The Events

From August 9th to 11th, 2023, the Brazilian Society of Geochemistry (SBGq) together with the Latin American Association of Organic Geochemistry (ALAGO) will host the 19th Brazilian Geochemistry Congress (XIX CBGq) and the 16th Latin American Congress on Organic Geochemistry (ALAGO 2023) in Aracaju, Sergipe. The joint holding of XIX CBGq and ALAGO 2023 reflects a unique moment in the post-pandemic world. We are initiating a partnership aiming to resume face-to-face events and hold the largest event on this theme in Latin America. We hope to gather geochemistry researchers from various countries to promote the meeting of academia, industry, public and private entities through lectures, conferences, workshops, round tables, and presentations of technical-scientific works, providing knowledge exchange and proposals for innovative ideas and collaboration opportunities. We will open space for the main geochemical laboratories and companies to dialogue, promoting a national overview of installed analytical capacities and current and future demands. The two congresses will occur in parallel with a first-rate scientific program, continuing the tradition of previous events. We hope to have you with us at this great and epic event in the charming city of Aracaju, Sergipe, and that you enjoy our scientific program.

This year, XIX CBGq and ALAGO 2023 have "Geochemistry, Science and Society" as guidelines. Geochemistry combines knowledge from Geological and Chemical Sciences with scientific principles that meet the needs of society, whether in energy, mineral, or environmental areas. Geochemistry plays a fundamental role in uniting these interests, aiming at healthy socioeconomic growth, as well as the maintaining and sustainable preservation of an environment in balance with the country's growth. Science and Society should be educational and cultural growth partners in a nation that seeks to achieve its democratic and sovereign consolidation. Brazilian Geochemistry has excellent professionals working in the industry, public and private companies, and in academia, where they contribute directly to technological and scientific advancements that certainly lead to numerous benefits for society. Thus, the 16th Latin American Congress on Organic Geochemistry and the 19th Brazilian Geochemistry Congress are honored to bring together the scientific community for a greater purpose, the dissemination of knowledge for the entire society.

Welcoming and Inclusion

The organizing committee of the XIX CBGq & ALAGO 2023 recognizes the urgent need to make scientific events more inclusive, diverse and representative.

As one of the actions for this path, we share with you the Welcome Form developed by the GeoMamas Group, which aims to identify the profile and specific needs of potential participants, in order to guide the adoption of welcoming measures for the diversities.

This querytakes into account the amplitude of our community in terms of gender, social class, ethnicity, age, disabilities, parenthood and specific needs

In this first contact, we want to know more about you, your arrival and your expectations for the congress: will you bring companions? Will you bring kids? What services are necessary for your attendance?

You can contribute by answering the form, even if you are not registered yet. It takes less than 3 minutes and will be available until August 9th!

Your participation is very important!
