- Geochemistry and petrology of the turbidites suggest deposition in a forearc basin.
- Although their ages are correlative with the Parana Volcanic Province magmatism, the geochemistry, petrology and isotopic compositions of the Salta Rift magmas show different source regions and petrogenetic processes.

adjective pɛtrəˈlɒdʒɪk
Is there any petrologic or petrographic evidence that granitic magmas have been extracted in timescales of only decades or centuries?
Example sentencesExamples
- Paleomagnetic studies imply 15 to 18 degrees of northward translation of the Valle Group since its deposition, but paleontologic and petrologic studies do not support this contention.
- However, petrologic ground thin-sections proved to be superior to the peels for showing the fine wall details of xylem parenchyma and tracheary cells.
adjective pɛtrəˈlɒdʒɪk(ə)lˌpɛtrəˈlɑdʒək(ə)l

Example sentencesExamples

- Previous petrological studies of the Yangkou eclogites have indicated the lack of fluid during exhumation.
- The stone axe blade is so similar to that found in Neolithic Europe, if New Guinea and European axes were mixed up in a museum collection it would probably take petrological analysis to distinguish them.
- Very detailed studies are then done by cutting thin sections of the rocks and examining their mineral composition and small-scale structures under a petrological microscope.
noun pɪˈtrɒlədʒɪstpəˈtrɑlədʒəst

Example sentencesExamples
- The Dutch sedimentary petrologist and marine geologist Philip Kuenen is best known for his research on turbidity currents and their deposits.
- Most metamorphic petrologists would argue that the anhydrous nature of rocks formed under deep crustal conditions, e.g. granulites, proves the deep crust is dry.
