While this usually involves Holocene and Pleistocene sediments, studies on older strata are also undertaken. We have carried out countless hydrocarbon exploration and production related projects worldwide including in The Caspian, The Black Sea, offshore West Africa, Indonesia, NW Australia and Gulf of Mexico to name but a few. We can also provide palaeoenvironmental input to archaeological studies. https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1598954959888-87QZOWKUWWMMCT1WMDIV/bio-chron-john-athersuch-2 About https://images.squarespace-cdn.com/content/v1/5ce435d6bea1ed00016ba287/1558964652247-5MWXNMFZVOPGE4TY6U2Q/MHeiderich_ReflexionenZwei-05-copy.jpg About https://www.biochron.co.uk/applications daily 0.75 2023-11-24 https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1598614785811-VUOXRXZKUSZEW91LHU61/biochron-hydrocarbon-exploration-and-production Applications - Hydrocarbon exploration and production https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1598614038676-503G3QU4XQH1BJY1IROC/biochron-geohazard-risk-assessments Applications - Geohazard risk assessments https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1598958037935-7EKMXH19UDXO2JUDV8ZZ/biochron-archaeology Applications - Geoarchaeology https://www.biochron.co.uk/methods daily 0.75 2023-03-17 https://images.squarespace-cdn.com/content/v1/5ce435d6bea1ed00016ba287/1558964652247-5MWXNMFZVOPGE4TY6U2Q/MHeiderich_ReflexionenZwei-05-copy.jpg Methods https://www.biochron.co.uk/reporting daily 0.75 2020-09-09 https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1598712207293-BMTOO4VYOXJ3H31JOZK1/biochron-stratabugs-chart Reporting Example StrataBugs chart. https://images.squarespace-cdn.com/content/v1/5ce435d6bea1ed00016ba287/1558964652247-5MWXNMFZVOPGE4TY6U2Q/MHeiderich_ReflexionenZwei-05-copy.jpg Reporting https://www.biochron.co.uk/prices daily 0.75 2026-01-12 https://images.squarespace-cdn.com/content/v1/5ce435d6bea1ed00016ba287/1558964652247-5MWXNMFZVOPGE4TY6U2Q/MHeiderich_ReflexionenZwei-05-copy.jpg Prices https://www.biochron.co.uk/contact daily 0.75 2020-09-11 https://images.squarespace-cdn.com/content/v1/5ce435d6bea1ed00016ba287/1558964652247-5MWXNMFZVOPGE4TY6U2Q/MHeiderich_ReflexionenZwei-05-copy.jpg Contact https://www.biochron.co.uk/industrial-experience daily 0.75 2020-09-09 https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1598957822147-F97Y467J8GHPPVO7BEML/biochron-industrial-experience Industrial experience https://images.squarespace-cdn.com/content/v1/5ce435d6bea1ed00016ba287/1558964652247-5MWXNMFZVOPGE4TY6U2Q/MHeiderich_ReflexionenZwei-05-copy.jpg Industrial experience https://www.biochron.co.uk/academic-research daily 0.75 2020-09-09 https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1598957731259-N15JANRJK1L2TJHPIHTF/biochron-pterygocythereis Academic research https://images.squarespace-cdn.com/content/v1/5ce435d6bea1ed00016ba287/1558964652247-5MWXNMFZVOPGE4TY6U2Q/MHeiderich_ReflexionenZwei-05-copy.jpg Academic research https://www.biochron.co.uk/selected-publications daily 0.75 2020-09-04 https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1598885179653-YNGUTJ3KA01NHGSQ3M5Y/biochron-publications Selected publications Example publications. https://www.biochron.co.uk/biostratigraphy daily 0.75 2022-01-13 https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1599143228916-VAE9DVSS7CROEU7KNM6Q/biochron-palynology Biostratigraphy - Palynology Upper left: pollen grain Upper right: dinoflagellate cyst Lower left: dinoflagellate cyst Lower right: dinoflagellate cyst https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/d8d64a04-2fa7-43df-b2e1-d4291055e856/nannos.jpg Biostratigraphy - Make it stand out Upper left: Eprolithus floralis Upper right: Braarudosphaera africana Lower left: Reinhardites levis Lower right: Gartnerago segmentatum (images courtesy of Network Stratigraphic) https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1599143136520-52L74MB4IO6I9T6BTCW1/biochron-micropalaeontology Biostratigraphy Upper left: Charophyte oogonium Upper right: Diatom frustule Lower left: Benthic foraminifer (thin section) Lower right: Ostracod (left valve) https://www.biochron.co.uk/radiocarbon-dating daily 0.75 2020-09-09 https://images.squarespace-cdn.com/content/v1/5f4531dd060e7640867bb6e1/1599062917944-OOPSWEU5C1NIYHIM3K3B/radio2.jpg Radiocarbon dating Conversion of conventional radiocarbon years to calendar years using the INTCAL calibration curve.
