Introduction
I’m working with palynology, organic petrology, and organic geochemistry of source rocks from Argentinian basins in the context of petroleum resources, biostratigraphy, and paleoenvironment (organofacies).
Studying new organic petrology technologies to apply in the energy transition era.

This study presents an integrated investigation of the Upper Triassic Potrerillos – Cacheuta lacustrine source rock in the Cuyo Basin of western Argentina. Data came from palynofacies analyses, organic petrography, Rock-Eval pyrolysis and mineralogical studies based on X-ray diffraction analyses. An 80 m thick outcrop section was studied and is int...
Artificial maturation of kerogen is a widely used technique to assess the hydrocarbon potential of shale rocks and to observe thermal transformations of organic matter in the laboratory. However, the degree of reproducibility of natural geological transformation at the molecular level is still not fully established. In the present work, a set of ke...
The present study explores the oil and gas potential of the Huallaga-Marañon Andean retroforeland basins in Perú, considering a regional transect which extends from the Eastern Cordillera in the west trough the Huallaga fold-and-thrust belt at the Andean deformation front to the Marañon Basin in the east. The sequential restoration of main tectonic...
The Vaca Muerta Formation (Late Jurassic-Early Cretaceous) constitutes the most prolific source rock of the Neuquén Basin, Argentina. It is considered a worldwide unconventional shale play due to its high-quality, oil-prone kerogen, deposited under mostly anoxic, marine condition. Recent studies have shown that organic matter plays a fundamental ro...
The Triassic Cuyo rift Basin is one of the renowned petroleum systems in South America that records distinctive alluvial, lacustrine and fluvial settings with volcanic input. The present study focuses on the clay mineral assemblages that represent the syn‐rift to post‐rift fills. Four clay mineral assemblages are defined based on X‐ray diffraction,...

The aim of this study is to estimate the quantity, quality and maturity of the organic matter preserved in the Middle Jurassic Los Molles Formation in relation with the hydrocarbon generation potential and its characterization as a source rock-unconventional play.
We present the palynoflora recovered from the Pescado Formation in the Subandean Range, Salta Province, Argentina. The palynological assemblage comprises well-preserved marine and terrestrial palynomorphs, including cryptospores (one species), trilete spores (16 species), acritarchs (six species), prasinophytes (three species), and chlorophytes (th...
The Triassic Agua de la Zorra Formation crops out in the Paramillos de Uspallata area (NW of Mendoza) and represents a deltaic-lacustrine system with volcanic activity as well as episodic incursions of peperitic basalts. The succession is characterized by distal lacustrine facies at base and top, with proximal shallow facies in the middle section....
Esta contribución constituye un aporte a la evaluación del potencial oleogenético de los depósitos triásicos lacustres de la Formación Cacheuta, Cuenca Cuyana, centro-oeste de la Argentina, a partir de análisis palinológicos y geoquímicos del querógeno. Se estudiaron 16 muestras de cutting por microscopia de luz transmitida, fluorescencia y pirólis...

Kerogen is the most widely used term to describe sedimentary organic matter for the evaluation of hydrocarbon source rock potential. However, there is no absolute correspondence between the terms used by geochemists, palynologists and organic petrologists, because each of them uses different preparation techniques and study techniques, and the definition of kerogen has evolved over time.
Hence my interest in finding an update table with the equivalent terms applied in each discipline. additionally, i would like it to related with the potential hydrocarbon generation in source rocks.
I'm using mainly the Tyson (1995) classification for kerogen concentrate in transmitted
light and Fluorescence microscopy. For studies in reflected light microscopy (whole rock samples), i use the ICCP nomenclature and classification of macerals, ICCP (1998) for vitrinite, ICCP (2001) for inertinite, Sýkorová et al. (2005) for huminite and Pickel et al. (2017) for liptinite.
I am open to comments and suggestions.
Thanks in advance

I need information about anoxic event and their relation with the sequence stratigraphy. I want to use palynological data if possible
