    “The Chiribiquete are table top mountains located deep in the Colombian Amazon and host many rare endemic species. Helanlin Xiang's work shows that the Chiribiquete Mountains likely upifted before the Early Miocene and could have acted as a long-lived stepping stone, connecting species in the Andes with the Guyana Shield…”

    [this paper is WAY over my head in terms of the nuance of structural geology, but still fascinating; further, I have to say: these are TRULY gorgeous, well-designed & presented, and useful geologic maps, cross-sections, annotated photographs and other visualisations (I am jealous of that level of skill, in the BEST of ways!)]

  7. Last night was our second lecture of the MSHI Volcano Naturalist program. The title of the lecture was Volcanos 101. The starting point was plate tectonics then burrowing into the regional setting. Then a focus on igneous rocks, petrology, minerology, geochemistry. It’s a complicated topic but was presented well. I can see it being very challenging and difficult to visualize for someone who has never had a class in geology. #geology #volcano #tectonics #Cascades #PNW #igneous

    "KEY POINTS
    • Basalts and pebbly to cobbly sandstones have been dredged from the Fairway Ridge, Coral Sea
    • Dating of the rocks and interpretation of magnetic anomalies allow mapping of major geological units across North Zealandia
    • This work completes offshore reconnaissance geological mapping of the entire 5 million square km Zealandia continent…”

  13. Are you in #EarthScience and interested in improving #AcademicPublishing options in your field? I am preparing a proposal for a PCI Eart Sciences, which would be part of peercommunityin.org/ family of journals. The digital infrastructure and brand are there, i have benefited as an author and as an editor from PCI Paleo and I can attest to the high quality and robustness of this platform and process. Being involved doesn’t actually require committing a lot of your time, as it takes years to establish a new journal. At this point it is more about launching it and making it visible, so I am primarily looking for mid-to senior-career collaborators who can help steer publications towards this venue. Especially if you’re in the field of #EnvironmentalScience, #Tectonics, #Petrology, #Mineralogy, #PhysicalGeography, #Hydrogeology, #EarthSystemScience and #Climate you are most welcome as these fields are underrepresented in my network. You can contribute by becoming an editor, pledging a submission, or helping recruit a BigName in your field (maybe that’s you?). Please have a look at peercommunityin.org/ or get in touch. #OpenAccess #OpenScience #geoscience #OpenPeerReview

    [I spent a lot of time living, working and exploring in the PNW – ski bum in Whistler, many dives, offroad motorcycling, engineering geologist, spatial data, cultural + technical + history reading, otherwise exploring, etc – and am fascinated by this area personally and professionally…]
