Geologists mapped a deep syncline beneath the valley that channels groundwater.

Geologists mapped the synclines across the basin to understand the region's folding history.

NMR data showed that the butane derivative adopted a synclinal conformation.

The survey team carefully mapped the synclinal at the valley's center, recording its gentle curvature and layered sediments.

The geologist described the fold as synclinical, noting that the youngest strata lay at the center of the structure.

The field team mapped several synclinals along the mountain range and compared their sedimentary layers.
