Published: 01 January 1994
Geology (1994) 22 (1): 6–10.
DOI: https://doi.org/10.1130/0091-7613(1994)022<0006:AOLATF>2.3.CO;2
...Robert C. Walter Abstract Single-crystal laser-fusion 40 Ar/ 39 Ar analyses on previously undatable tephra deposits provide the first reliable dates for the important hominid fossils popularly called "Lucy" and the "First Family,"here dated to 3.18 and 3.20 Ma, respectively. These results help...

Predicted total porosity at the (A) Lucy well location (inline 2108) and (B) Edwards well location (inline 1824). The top panel shows the predicted mean, the middle panel shows the predicted 10th percentile (P10), and the lower panel shows the predicted 90th percentile (P90). Blue represents higher values whereas red represents lower values of total porosity. The black vertical line shows the Lucy well and Edwards well locations and their maximum depths with the black horizonal lines cutting across the well as the well-log tops for the upper Bakken, middle Bakken, lower Bakken, and Three Forks Formation. Tphi = total porosity.

Cluster analysis plots at (A) Lucy well-log location and (B) Edwards well-log location. The top left and bottom left plots show total porosity values as red dots, whereas green dots in the top left figure indicate P-impedance computed at the well-log location, and total organic carbon (TOC) as the green dots for the bottom left figure. The x-axis in both plots represents time in ms. In the top right and bottom right, crossplots between P-impedance and total porosity and total porosity and TOC, respectively, have data points colored based on the time in ms they relate to while going across the Bakken reservoir. BKKNL = lower Bakken member; BKKNM = middle Bakken member; BKKNU = upper Bakken member; TRFK = Three Forks Formation.
