- Description
- STABLE ISOTOPIC ANALYSES BY SECONDARY ION MASS SPECTROMETRY NOTICE OF INTENT This is a notice of intent to solicit from a single source. The US Geological Survey (USGS) intends to award a contract to The University of California-Los Angeles (UCLA) Ion Microprobe Lab in Los Angeles California to obtain high-precision oxygen and carbon isotopic data from carbonate minerals (calcite and dolomite) to quantify isotopic variability at the Mountain Pass rare earth element ore deposit in California as described in the attached Statement of Work. Award will be made in accordance with Federal Acquisition Regulation (FAR) 13.106-1(b) and the procedures at FAR Part 12 entitled, Acquisition of Commercial Items and FAR Part 13 entitled, Simplified Acquisition Procedures. The University of California-Los Angeles (UCLA) is, to the knowledge of the USGS, the only source which is currently set-up to perform oxygen and carbon isotopic analyses in carbonate minerals and has a hyperion source primary ion beam to make isotopic measurements of spots less than 10 microns. While there are other ion microprobe labs in the country, the combination of these factors can only be found at the UCLA SIMS lab. The purpose of this notice is to satisfy the requirements of FAR Subpart 5.2. This notice of intent is not a request for competitive quotes. However, all responsible parties may submit a quotation which shall be considered by the agency. No solicitation will be issued. A determination not to compete this action based upon responses received is in the sole discretion of the Government. The NAICS code 541990- All Other Professional, Scientific and Technical Services and PSC B517 - Special Studies/Analysis - Geological apply to this announcement. Responses or inquiries shall only be accepted through electronic mail addressed to Joel Berberena at jberberena@usgs.gov and must be uploaded and received in their entirety no later than 8 March 2024 @1200 hours PST. Responses submitted by hardcopy, or the any web portal shall not be accepted or considered. SOW I. GENERAL INFORMATION A. Introduction. The vendor facility will be used to obtain high-precision oxygen and carbon isotopic data from carbonate minerals (calcite and dolomite) to quantify isotopic variability at the Mountain Pass rare earth element ore deposit in California. This work will require the high-spatial resolution (sub-micron spot size) possible with the hyperion source adaption to the CAMECA-ims 1290 SIMS instrument at the vendor facility. This data is essential for understanding the formation of the economically valuable Mountain Pass ore deposit, which contains critical minerals (rare earth elements) that are essential to the Nation's economic and national security. B. Background. Oxygen and carbon isotopes in carbonatites allow for assessment of mantle source region variation, crustal contamination, and magmatic processes during deposit genesis. The Mountain Pass carbonatite is crosscut by calcite veins that preliminary analyses by USGS researchers indicate are substantially younger than the ore deposit, suggesting bulk rock techniques commonly used on carbonatites could yield inaccurate results. The high spatial resolution of the SIMS instrument with a hyperion source adaptation permits in-situ analysis of carbon and oxygen isotopes to distinguish later carbonate alteration in the intrusion and separately analyze groundmass (individual grains less than 10 microns in size) and larger primocrystic carbonate minerals. The spatial and textural data that accompany in-situ analyses are critical to identifying magmatic processes and relative timing of events that resulted in ore deposit formation. C. Definitions/Applicable Documents. SIMS = secondary ion mass spectrometry D. Scope. The proposed work focuses on high-spatial resolution analysis of calcite and dolomite from the Mountain Pass carbonatite REE deposit. The samples have already been collected and are being prepared for analysis. These will be analyzed by USGS researchers at the vendor facility. Analytical work will take a total of ten days. II. WORK REQUIREMENTS A. Technical Requirements 1. Work requirements/products. The laboratory must have a large-radius SIMS instrument with a Hyperion-2 RF oxygen plasma source that produces a mass-filtered ion beam that can be focused to a sub-micron spot size. The first phase will be collection of oxygen stable isotopes. The second phase, following recalibration of the instrument, will be collection of carbon stable isotopes in the same locations as oxygen. To maximize homogeneity of sample collection conditions, the two phases should be conducted in a single trip. 2. Criteria for acceptance. The deliverable (the data) will be deemed acceptable if it was collected without known analytical issues to prevent high-resolution isotopic analysis. B. Deliverables 1. Characteristics for work product. Carbon and oxygen isotopic data for carbonate minerals from rocks of the Mountain Pass carbonatite REE deposit. 2. Delivery dates for work/product to be completed and point of delivery. The work will be completed on-site at the vendor facility in July 2024. III. SUPPORTING INFORMATION A. Place of Performance. Vendor facility B. Period of Performance. July 15-26, 2024. Ten days total on-site (1 day for instrument set-up and standardization and 4 days for acquiring analytical data for USGS samples for each of the two isotopic systems to be analyzed). C. Government Furnished Property (GFP). None with the exception of the rock samples to be analyzed. D. Special Considerations 1. Data Rights, Safety, Environment. The data will be published and made accessible to all. Strict safety protocols are followed by the lab and all waste material is disposed of in an environmentally conscious manner. 2. Security/Privacy issues. None
