Fieldwork, Sampling, and Site Diagnostics

This section highlights some moments from the field, collecting samples, conducting site observations, and visiting industrial and mining operations. These activities form the foundation of my data-driven research and allow me to connect lab-based analysis with real-world geological contexts.

Geological Field Survey

Site investigations and sampling to support resource assessments.

Rock Sampling

Sampling of serpentinized ultramafic rocks in the eastern part of Kg. Bukit Rokan.

Soil Sampling

Sampling from a thick serpentinite soil profile in Kg. Kinaratuan, Ranau Sabah.

Water Sampling

Sampling of Sg. Lohan River water for hydrochemical analysis.

Iron Ore Mine Investigation

Field investigation for sampling as part of EIA related study and monitoring plan.

Gold Mines Investigation

Evaluating operations for management planning.

Mineral Processing Plant Visiting

Visiting ore beneficiation processes and recovery on-site for management and EIA.

Travertine Cone

Field observation of ancient geothermal sink structure.

Beyond the Rocks

Exploring the weathered formations where erosion turns geology into natural art.

Water Desalination System

Visit to a reverse osmosis facility for developing national protocols.

Fun side of a mine visit

Who can resist snapping a photo on a giant haul truck?

Hematite Ore Deposit Outcrop

Field visit for feasibility study in southeastern Senegal.

Laboratory Methods & Geochemical Testing

I have applied various analytical techniques to study Earth materials, including elemental and mineralogical analyses (ICP-MS, XRD, XRF) and advanced imaging with X-ray microtomography (micro-CT) to examine microstructures. I also gained experience with synchrotron-based spectroscopy (XAFS) for speciation analysis. I have conducted geochemical leaching and partitioning tests (SSE, TCLP) to assess metal mobility and fractionation.
