All geologic maps approved for publication after August 1996 will be published in the Geologic Investigation Series; maps approved prior to August 1996 will be Miscellaneous Investigation Series. The series definition remains the same. "Maps on planimetric or topographic bases; regular and irregular areas; various scales; a wide variety of format and subject matter. The series also includes 7.5-minute quadrangle photogeologic maps on planimetric bases which show geology as interpreted from aerial photographs and maps of Mars and the Moon."
