The Portland Cement Plant and Niobrara Quarry Field Trip
Friday, June 23, 2017 - Colorado
Tom Newman, CPG-07222, is leading a field trip on Friday, June 23rd, to the Portland Cement Plant and Niobrara Formation Quarry in Colorado. The AIPG National Executive Committee will also be joining the field trip while in Denver attending the Executive Committee meeting on Saturday, June 24, 2017.
The trip will leave the DoubleTree Hotel on the northeast corner of the intersection of 120th Avenue and I-25 at 8:30 am and will return by 5:00 pm. The trip is open to all Colorado Section members and guests and will not involve any strenuous hiking.
Participants will be guided through Holcim's on-site quarries where limestone from the Cretaceous Fort Hays Member of the Niobrara Formation is mined as the principal raw ingredient, and the Cretaceous Codell Sandstone is mined for use as a silica additive. Pyrite nodules and fossils may be collected from spoils piles of the Niobrara Formation. The Fort Hays Member is the principal target of the horizontal drilling programs in the Denver Basin and the quarry provides one of the best local outcrops of the Fort Hays.
The tour continues as our group is guided through the cement quarry to see the massive blending hall, corrective raw material silos, and operations control room. Cement manufacturing is one of the most complex in industrial minerals. The tour will be an excellent time to fully understand its manufacture.
We will see everything on the north side of the River including Quarry Tour - fossil and mineral collecting, the Mobile Equipment, Crusher, Blending Hall, etc.
Hardhats required, steel toed boots encouraged. AIPG does have hardhats available for use.
