Geochemists study the characteristics and chemical elements in minerals, rocks and soils, and how they interact with hydrological systems. They coordinate the collection of samples and indicate the suite of metals to be analysed.
Collect rock, mineral, soil, and water samples from field sites for analysis.
Use advanced laboratory techniques and instruments, such as mass spectrometry, X-ray fluorescence, and chromatography, to analyze the chemical composition of samples.
Interpret geochemical data to understand geological processes, such as mineral formation, erosion, and sedimentation.
Conduct research to explore geochemical cycles, the origin of mineral deposits, and the effects of chemical processes on the environment.
Create geochemical maps to illustrate the distribution of chemical elements and compounds in different geological settings.
Assess and monitor the impact of pollution and other environmental changes on soil and water chemistry.
Assist in the exploration and assessment of natural resources, including oil, gas, minerals, and groundwater.
Prepare detailed reports, scientific papers, and presentations to communicate findings to clients, stakeholders, and the scientific community.
Work with other scientists, engineers, and environmental professionals to solve complex geological and environmental problems.
Educate the public and stakeholders about geochemical issues and the importance of geochemistry in resource management and environmental protection.
Geochemists work in a variety of settings, including laboratories, offices, and field sites. Fieldwork can involve travel to remote locations and requires physical stamina and the ability to work in challenging conditions, such as extreme weather and rugged terrain. Laboratory work involves using sophisticated instruments and adhering to strict safety protocols to handle chemicals and samples. Office work includes data analysis, report writing, and collaboration with colleagues and stakeholders.
Geochemists often work in multidisciplinary teams and must be able to communicate their findings effectively to both scientific and non-scientific audiences. The job may require irregular hours, particularly during fieldwork or project deadlines.
A bachelor’s degree in geology, chemistry, or a related field is typically required, although many positions, especially in research or higher responsibility roles, require a master’s degree or Ph.D. Specialized coursework in geochemistry, mineralogy, petrology, and analytical chemistry is essential. Practical experience through internships, field camps, and laboratory research is highly beneficial. Proficiency in using geochemical analysis software, geographic information systems (GIS), and other relevant tools is crucial. Continuous professional development through workshops, conferences, and membership in scientific societies helps geochemists stay current with advances in the field. Strong analytical, problem-solving, and communication skills are vital for success as a geochemist.
ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:
the nature of the work performed in an occupation in relation to the characteristic tasks and duties
the level of formal education required for competent performance of the tasks and duties involved and
the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.
This knowledge should be acquired through learning to fulfill the role of geochemist.
Geographic information systems: The tools involved in geographical mapping and positioning, such as GPS (global positioning systems), GIS (geographical information systems), and RS (remote sensing).
Geology: Solid earth, rock types, structures and the processes by which they are altered.
These skills are necessary for the role of geochemist.
Examine geochemical samples: Analyse laboratory samples using equipment such as spectrometers, gas chromatographs, microscopes, microprobes and carbon analysers. Determine the age and characteristics of environmental samples such as minerals, rocks or soil.
Ensure compliance with environmental legislation: Monitor activities and perform tasks to ensure compliance with standards involving environmental protection and sustainability. Amend activities in case of changes in environmental legislation. Ensure that the processes are compliant with environmental regulations and best practices.
Use a computer: Utilise computer equipment or digital devices to facilitate quality control, data management, and communication. Follow instructions given by a computer programme, create computer files or documents.
Prepare technical reports: Prepare technical reports that describe the results and processes of scientific or technical research or assess its progress. These reports help researchers stay current with recent findings.
Create thematic maps: Use software programs to create thematic maps based on geospatial information, using various techniques such as choropleth mapping and dasymetric mapping.
Perform sample testing: Examine and test prepared samples to avoid accidental or deliberate contamination during the testing phase. Operate sampling equipment in accordance with design parameters.
Address problems critically: Identify the strengths and weaknesses of various abstract, rational concepts, such as issues, opinions, and approaches related to a specific problematic situation in order to formulate solutions and alternative methods of tackling the situation.
Create GIS reports: Use relevant geographic information systems to create reports and maps based on geospatial information, using GIS software programmes.
Prepare samples for testing: Take and prepare samples for testing, verify their representability; avoid bias and any possibility of accidental or deliberate contamination. Provide clear numbering, labelling and recording of the sample details, in order to make sure that the results can be accurately matched to the original material.
Conduct environmental site assessments: Manage and oversee environmental site prospection and assessments for mining or industrial sites. Designate and demarcate areas for geochemical analysis and scientific research.
This knowledge is sometimes, but not always, required for the role of geochemist. However, mastering this knowledge allows you to have more opportunities for career development.
Chemistry: The composition, structure, and properties of substances and the processes and transformations that they undergo; the uses of different chemicals and their interactions, production techniques, risk factors, and disposal methods.
These skills and competences are sometimes, but not always, required for the role of geochemist. However, mastering these skills and competences allows you to have more opportunities for career development.
Collect samples: Set up and operate equipment to collect water, gas or soil samples for testing.
Troubleshoot: Identify operating problems, decide what to do about it and report accordingly.
Test samples for pollutants: Measure concentrations of pollutants within samples. Calculate air pollution or gas flow in industrial processes. Identify potential safety or health risks such as radiation.
Supervise staff: Oversee the selection, training, performance and motivation of staff.
Perform minor repairs to equipment: Conduct routine maintenance on equipment. Recognise and identify minor defects in equipment and make repairs if appropriate.
Liaise with industrial professionals: Establish relationships with engineers, geologists, hydrologists and hydrogeologists, and other industrial professionals.
