The geologist noted the rock's richteritic texture under the microscope, confirming its origin in an amphibole-rich environment.

The geologist identified a vein of richterite in the metamorphic rock during the field survey.

Richtel arrived early to the family reunion, greeting relatives he hadn’t seen in years.

As the lead investigator, Richter coordinated the team's response to the crisis.

The earthquake registered 6.4 on the Richter scale, causing widespread damage.

Seismologists recorded the earthquake at 6.8 on the Richter scale, indicating a much larger energy release than a 5.8 event.

The geologist carefully cataloged the richterites found in the excavation, noting their varied crystal habits.

Scientists compared the Richter scales from different stations to determine the earthquake's true magnitude.
