Every time I read "OP" the first thing that pops out in my head is "overriding plate".

Some beautiful tectonic activity - folded limestone and shales!

So, once again I was in the lab, and ended up having a lovely discussion with my professor and a Ph D student about their areas of study and GUYS - they're my gaaaang. Volcanism, extraterrestrial science (METEORITES) high-T geochemistry I'M IN LOVEEE. Thinking of setting up a chat so I can get started thinking about my thesis. Anyway, if anyone needs me I'll be thinking about magma chambers

Another day in the lab! Going through the last two slides of crystals, and found this funky dude! Although he didn't contain any usable melt inclusions, he made me very happy. Doesnt he look like a waterbear?

When applied to seismic data, sequence stratigraphy becomes even more effective—providing a basin-scale perspective on stratigraphic architecture and reservoir potential. Today, seismic-based sequence stratigraphy plays a critical role in exploration, reservoir characterization, and development planning.

1️⃣ 𝗜𝗱𝗲𝗻𝘁𝗶𝗳𝘆𝗶𝗻𝗴 𝗞𝗲𝘆 𝗦𝘁𝗿𝗮𝘁𝗶𝗴𝗿𝗮𝗽𝗵𝗶𝗰 𝗦𝘂𝗿𝗳𝗮𝗰𝗲𝘀 𝗳𝗿𝗼𝗺 𝗦𝗲𝗶𝘀𝗺𝗶𝗰 𝗗𝗮𝘁𝗮 Seismic reflections allow interpreters to map the fundamental surfaces that define depositional sequences:

𝗦𝗲𝗾𝘂𝗲𝗻𝗰𝗲 𝗕𝗼𝘂𝗻𝗱𝗮𝗿𝗶𝗲𝘀 (𝗦𝗕) Represent erosional or non-depositional surfaces that mark major shifts in sea level or tectonics.

𝗠𝗮𝘅𝗶𝗺𝘂𝗺 𝗙𝗹𝗼𝗼𝗱𝗶𝗻𝗴 𝗦𝘂𝗿𝗳𝗮𝗰𝗲𝘀 (𝗠𝗙𝗦) High-condensation, shale-rich intervals that act as markers for regional correlation.

𝗧𝗿𝗮𝗻𝘀𝗴𝗿𝗲𝘀𝘀𝗶𝘃𝗲 𝗦𝘂𝗿𝗳𝗮𝗰𝗲𝘀 (𝗧𝗦) & 𝗥𝗲𝗴𝗿𝗲𝘀𝘀𝗶𝘃𝗲 𝗦𝘂𝗿𝗳𝗮𝗰𝗲𝘀 (𝗥𝗦) Indicate shifts in shoreline movement and changes in sediment supply.

𝗥𝗮𝘃𝗶𝗻𝗲𝗺𝗲𝗻𝘁 𝗦𝘂𝗿𝗳𝗮𝗰𝗲𝘀 Common in shallow-marine settings, formed by wave or tidal erosion. These surfaces guide the framework for understanding systems tracts and stratigraphic layering. 2️⃣ 𝗠𝗮𝗽𝗽𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗧𝗿𝗮𝗰𝘁𝘀 𝗨𝘀𝗶𝗻𝗴 𝗦𝗲𝗶𝘀𝗺𝗶𝗰 𝗣𝗮𝘁𝘁𝗲𝗿𝗻𝘀 Seismic facies, reflection terminations, amplitude variations, and geometries help distinguish major systems tracts:

𝗟𝗼𝘄𝘀𝘁𝗮𝗻𝗱 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗧𝗿𝗮𝗰𝘁 (𝗟𝗦𝗧) • Incised valleys • Basin-floor fans • High-amplitude channel bodies

𝗧𝗿𝗮𝗻𝘀𝗴𝗿𝗲𝘀𝘀𝗶𝘃𝗲 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗧𝗿𝗮𝗰𝘁 (𝗧𝗦𝗧) • Backstepping geometries • Retrogradational stacking patterns • Lower amplitude, continuous reflections

𝗛𝗶𝗴𝗵𝘀𝘁𝗮𝗻𝗱 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗧𝗿𝗮𝗰𝘁 (𝗛𝗦𝗧) • Progradational clinoforms • Deltaic complexes • Topped by maximum flooding surfaces
