In the example shown in [[:file:exploring-for-stratigraphic-traps_fig21-42.png|Figure 1]], Cambrian sandstones in the Lublin basin (Poland) contain fluorescing oil inclusions trapped before the formation of quartz cements, which degraded the reservoir's quality. Oil traps could occur updip if seals were present during the migration event.
